Yarway Blow-Off Valves


(Click here for Blow-Off brochure)


General description of Blow-Off Valves

Basic requirements for the design and use of blow-off valves are established by the ASME Power Boiler Code, Section 1.  The general form of a valve, the materials of its construction, allowable boiler pressures, and the installation of the valve are all determined by the code.
Yarway blow-off valves are designed in conformance with all code requirements1.Because the primary purpose of a blow-off valve is removal of dirt, sediment and scale, the boiler code requires that valves which have dams or pockets in which sediment can accumulate cannot be used in blow-off service. This means that ordinary globe valves cannot be used as blow-off valves. Yarway valves are especially designed for the punishment of blow-off service in boiler systems with pressures of 3,206 psig.
The rugged construction of these valves can successfully withstand the combination of problems inherent in the service - a service in which high pressures result in high velocities which can cause wire drawing and cavitation of metal surfaces. The valves must also withstand the corrosive environment created by acid cleaning of boilers, and the potential wear problems caused by precipitated solids. The valves are also helpful in maintaining boiler level surge within desirable limits during quick startup of high pressure systems. Two broad categories of Yarway blow-off valves are available; those that operate on a sliding principle and those that operate on a seat-and-disc principle.
1. ASME Section 1, ANSI B31.1, ANSI B16.34.

  • High Dependability - One-piece forged body without pressure welds, seal welds, pressure-containing threads or gaskets, body/bonnet joints, or any of their related problems.

  • Greater Durability - Solid Stellite disc and seat ring all but eliminates cracking. Extra thickness of the seat ring also provides enough material to renew the seating surface over and over again.

  • High Flow Capacity - Generous port sizes and disc retraction well beyond that required for optimum flow. These features help to minimize flow velocities and, therefore, decrease the erosive forces which shorten the life of the seat and disc.

  • Available Off-The-Shelf - An in-depth stocking program makes Welbond valves available to you directly off-the-shelf (socketweld ends standard to 21/2”).You can be certain when you need a valve you’ll have it.

  • Convertible Feature - The complete pre-machining of each Valve body means one of the backseat designs can be converted to the other, simply by reassembly with alternate backseat bushing.

Yarway Hy-Drop® Throttling Valve -- Controls the destructive forces inherent in high pressure drop service through rapid energy dissipation


(Click Here for Hy-Drop Valves Brochure)

General Description
Valves used for throttling services have always been subject to rapid deterioration in the form of erosion, cavitation damage, and wiredrawing of vital parts. Even venturi valves and other special configurations are vulnerable.
The Hy-Drop® Throttling Valve embodies a unique concept, which so controls the destructive forces inherent in high-pressure- drop service that deterioration of parts is virtually eliminated. Rapid energy dissipation is essential to the throttling process, and the Hy-Drop® valve actually encourages this at the same time containing its destructive capability.
Hy-Drop® Throttling Valve  The basis for this concept is in the configuration of the flow path as determined by the shape of the valve disc and seat. Fluid flowing through the annulus between disc and cylindrical seat accelerates smoothly until it reaches the blunt end of the disc. At this point, the flow area increases abruptly at its center and the resulting pressure drop at the core of the flow path causes rapid expansion of the fluid toward the core. Thus, the essential vaporization and turbulence occur at the center, within a layer of unvaporized fluid which continues to flow along—and protect— the sleeve wall. With this configuration, the vaporization process is so efficient that the vapor formed is momentarily super-saturated and the remaining liquid subcooled, until equilibrium is re-established a short distance down the sleeve passage.

Applications: The Hy-Drop® Throttling Valve is designed for continuous blowdown, but also works well for sampling, high pressure vents, boiler feed pump bypass relief, high pressure drop services associated with erosive and wiredrawing characteristics—or where velocity is sufficient to destroy valves of conventional globe or even venturi designs.

Hy-Drop®  Features and Benefits

  • Dual range throttling - primary range plus a super capacity blast range

  • Rapid energy dissipation - controls the destructive forces inherent in high pressure drop service.

  • Accurate and repeatable settings - micrometer dial assures setting accuracy and positive resetting capability.

  • Quick-change disc - insert an interchangeable stem-disc into the same valve body to convert from one orifice size to another.

  • Guided-disc - eliminates disc vibration and chatter.

  • Dual-purpose disc - separate surfaces for shutoff and throttling.

  • Stellite seat - resists corrosion and wiredrawing.

  •  In-line repair - Yarway reseating tool can be used to cut a new seat in-line.

  • Available in ASME SA-182 Grade F22 or ASME SA-105 body material

 

Yarway Gun-Pakt® Expansion Joints Yarway joints are made in single end and double end types. Double end joints are frequently installed in place of two single end joints to reduce the number of pipe joints, or to meet local space conditions. On flanged end joints, end flanges are welded to sleeve and body in the single end type, and to both sliding sleeves in the double end type. Flange dimensions and drilling are according to ANSI B16.5 Steel Pipe Flanges and Flanged Fittings. Welding end joints have butt-welding connections for steel pipe lines. Fabricated steel anchor bases may be welded to the joint in any position specified. All double end joints have anchor bases, but single end joints are available with or without bases. Steam lines should be drained of condensate at low points to prevent damage due to water hammer, corrosion, sagging, etc. When used, drains should be connected to a suitable strainer and steam trap; when not used, the drain must be plugged. Yarway joints are available in sizes from 1-1/2" to 12". They are standard for 150 psi and 300 psi service. The flanges are drilled per B16.5 Class 150 (150 psi service) or Class 300 (300 psi service). Note the rating for the expansion joint is a maximum allowable pressure rating and not an ANSI Class. For example, a 300 psi expansion joint can be used only in a service where the maximum fluid pressure is 300 psig (at all temperatures). Maximum fluid temperature is 500 F for all packings.
Yarway Series YTF-30 Float and Thermostatic Steam Traps

This range of Series YTF-30 float and thermostatic steam traps covers higher capacity applications up to 125 psig.
Yarway Float and Thermostatic steam traps are designed to freely remove large quantities of condensate and air from unit heaters, space heaters, water heaters, converters, pressing machines and all steam process equipment. These traps are especially well suited for applications having low pressure differentials but needing higher condensate capacity. Besides industrial applications, due to their quiet operation, they are also used in institutional applications, such as hospitals. All working parts of Yarway Float and Thermostatic traps are made of corrosion resistant stainless steel for longer service life and are attached to the cover casting for easy access. Designed for in-line servicing, the unit may be inspected and parts replaced without breaking any pipe connections. A stainless steel bellows-type air vent is used instead of the more commonly used phosphor-bronze element to provide greater efficiency, improved protection against sudden surges in the flow of condensate and resistance to corrosion.

Yarway 4300 Series TempLow® Steam Desuperheater

Features and Benefits 
For precise and economical control of steam temperature, the Yarway probe-type TempLow® desuperheater automatically introduces cooling water into steam flow in response to a pneumatic or electric control signal. The Yarway desuperheater represents a major advance in the design of this type or equipment. It has an unusually high turndown ratio - double that of units previously available. This permits its use in systems with wide fluctuations in steam flow rate. Small enough to mount through a 3-inch (NW 80) flange in the steam line, it includes features previously found only in larger, more space- consuming desuperheater units.  Water pressure 50 to 1600 psi [3.4 to 110 bar] above steam pressure is employed to generate thin-film, conical sprays which are injected into the steam flow through a series of vortex spray nozzles. The fine sprays evaporate rapidly in the steam, thereby minimizing the tendency for spray water to accumulate in the line. A separate water control valve is unnecessary because water flow control is a function of the desuperheater itself. Easy Installation 
• Installation in straight, vertical or horizontal pipe. 
• Minimal headroom is required for mounting the unit in line.
 • Only standard connections are involved for all sizes: 1-inch [NW 25] water; 3-inch [NW 80] steam. 
• Few components are required. 
• No atomizing steam or pipeliners (which complicate installation) are required. 
• Only 15 feet of straight run piping down stream.
Yarway Remote Liquid Level Indicator

Yarway Process Thermostatic Steam Traps

The Right Trap For The Right Application Whenever you’re faced with a process application, it’s not enough to just select any steam trap to solve your problem. Instead, remember to match your application with the correct steam trap technology. With Yarway process thermostatic traps, you’ll find a range of solutions available to match almost any application you face. But that solution is only as valuable as your understanding of the problem you are trying to solve. Variables such as steam pressure, condensate load, ambient conditions, air venting, water hammer, dirt, and corrosion must be carefully considered when choosing the right trap for the right application. Even upstream and downstream piping design plays a very important role in your final selection. With Yarway, you’re not alone in making these tough decisions. You are supported every step of the way with valuable programs like Yarway’s Complete Steam Trap Sizing and Selection software.

Yarway Non-Repairable Drip and Tracer Steam Traps
It all comes down to protection Regardless of the temperature and pressure characteristics of steam line drips or tracers, there’s one absolute requirement for any steam trap you choose — protection. Whether your system includes steam lines, turbines, control valves, risers, expansion loops, steam jacketed pipes, valves, and pumps — or simply companion piping — a steam trap must offer protection day after day. More often than not, that also means consistent performance in less-than-perfect conditions. That’s why it’s important to understand your application in as much detail as possible before you select a drip or tracer steam trap. Variables such as: steam pressure, condensate load, ambient conditions, air venting, shock, vibration, water hammer, dirt, and corrosion must be considered when making your trap selection for steam line drip, process line tracer, winterization tracer, instrumentation tracer, and steam jacketed tracing, as well as small process application.



Purpose: To remove condensate from piping to prevent damage to the piping and control valves, while assuring that production steam users receive dry steam. 
Steam trap requirement: Adequately sized drip pockets on the bottom of piping or upstream of heat exchanges, collect condensate which then flows to the steam trap. The trap should discharge the condensate quickly. 
Steam pressures and temperatures: Generally constant, with some seasonal variation. Of all industrial steam trapping applications, these are the higher pressures often exceeding 600 psi. Design pressures and operating pressures can be different and superheat is frequently encountered. 
Condensate loads: Relatively small and constant while in normal operation, typically to 50 or 100 lb/hr. Startup loadscan be heavier. Boiler carry-over produces slugs of condensate which are unpredictable in magnitude and frequency. Desuperheaters that are malfunctioning can produce unexpectedly high loads. 
Drainage to trap:
Usually by gravity with the steam trap installed below the steam line. Occasionally piping in trenches or underground have steam traps installed above the pipe, but the condensate collecting point is below the pipe. This is called lift drainage and requires a lift fitting. 
Ambient conditions:
Variable. Freezing is the more common concern. 
Air venting:
Need is minimal. Pipe lines frequently have separate vents. Startup may present the most common need. Under running conditions, CO2 may be a problem.
Shock, vibration, water hammer: Generally from inadequate drainage of condensate, which moves at high velocity (5,000 - 10,000 fpm). Thermal ratcheting may also occur at startup.
Dirt and corrosion: If dirt and corrosion exist at the steam trap, consider what may be happening at the equipment being protected. A common source of foreign matter is packing used to seal leaks. The use of some amines and hydrazine can present “dirt” problems. 
Steam trap installation:
If bypasses around a trap station are installed and utilized during warm-up, consider installing a trap downstream of the steam blow if the bypass is left open.

Yarway HP series high pressure bimetallic steam traps


High Pressure Steam Traps bimetallic
(Click here for brochure)

Models:

  • HP456
  • HP-80
  • HP100/-150
HP Series steam traps are designed for high pressure applications such as steam power generation by electric utilities and industry. These traps are highly energy efficient, because they operate at sub-cooled temperatures (like all bimetallic traps). Steam never reaches the valve because condensate actually seals off the valve seat area where steam loss could occur. The bi-metallically actuated valve can be adjusted externally, to provide more or less sub-cooling, without closing off the steam supply, and the traps are repairable in-line by the use of factory set (but subsequently adjustable) replacement internals. The traps include a full size screen. The flow is heavy when sub-cooling is great. Low flows occur with low degrees of sub-cooling.

During critical low load periods, centrifugal feed pumps need a reliable recirculation system to prevent pump instability and overheating. Because many such systems are constructed of a number of components, the systems can become both complex and costly, requiring substantial outlays for design, installation and maintenance. Yarway’s 5300 ARC valve, on the other hand, is a complete system within itself. It actually performs four separate functions within the pumping circuit - all within one compact body. Essentially, the 5300 ARC valve is a check valve installed in the main line. But it also acts as the sensing and powering element which pilots the operation of a recirculation control valve. The sensing system responds to changes in flow rather than pressure.  The control valve incorporates a pressure reducing device that divides recirculation flow and guides the resulting streams through successive 90° turns to dissipate the destructive energies of high pressure while controlling fluid velocity.  But perhaps even more importantly, the 5300 ARC valve recirculates only that flow needed to cool a feed pump at critical times of low load rather than permitting a continuous recirculation flow. The valve therefore saves the electrical power that continuous recirculation would consume, which can cost several thousand dollars per year.

One valve, four functions
Flow sensing that actuates the pilot for the bypass control valve which permits passage of a limited flow of cooling liquid during low load periods. This flow is delivered to the cascade element which dissipates the energy for quiet, safe delivery to the deaerator, condenser or other low pressure sink. Check valve prevents reverse flow through the feed pump.
