Special Valves

  • Foot Valve
    Foot valve is a special type of check valve that has a built-in strainer.It is installed at the intake side of a suction pipe and pump.its purpose is to prevent the loss of prime when the liquid source (wet well) is lower than the pump.prime is designed as the charge of loquid required to begin pumping action and priming is the process of filling the pump and suction pipe with liquid.The check valve part of the foot valve opens when the pump starts to allow liquid to enter the suction pipe and pump.when the pump stops the check valves closes and prevents the liquid from emptying.thus the foot valve eliminates the need to prime the pump each time it is started.the strainer component of the foot valve helps to romove unwanted debris from the liquid that may cause damage to the pump.
  • Sleeve Type Soft Sealing Plug Valve
    Sleeve Type Soft Sealing Plug Valve are non-lubricated quarter-turn valves that achieve sealing through the use of a compressible sleeve as a sealing member. In many applications they operate virtually maintenance free for decades.Our valves are used for on/off and throttling service in demanding process applications with media temperatures ranging from -29℃ to 180℃. Standard sizes from 1/2" to 14", ANSI class 150-900. Body & plug materials range from cast steel and stainless steel to other special alloy steel.
  • High Pressure Threaded Needle Valve
    High Pressure Threaded Needle Valve are an ideal option for isolating or throttling applications. The self centering, non rotating stem ensures perfect seating. The rigid design gives repetitive bubble tight shut off, easy Standard Specifications :End connection : NPT / BSPP / BSPT Maximum working pressure :700 bar / 10000 PSI at 1000 C(see pressure temperature chart on Page No. 4 for higher temperature applications)Material : 316 SS / 316L SS / 304 SS / Carbon steel MOC in accordance with NACE MR0175 is available on request.Monel, Inconel, Hastelloy, Duplex steel are also available on request. Gland packing : PTFE / Graphite.
  • Pilot Operated Pressure Reducing Valve
    Pilot Operated Pressure Reducing Valve, similar to Spirax Sarco Design, mainly used for steam system to reduce pressure, which is superior to normal piston type steam pressure reducing valve.Pressure reducing valve the new type pilot extra-huge membrane pressure reducing valve developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.Pilot Pressure Reduce Valve can realize the temperature control, upsteam pressure control, remote switch control. Super high sensitivity guide type diaphragm actuator provide a super high sensitivity regulate and flow control.
  • Rubber,PTFE,PFA,F46 Lined Diaphragm Valve
    Rubber,PTFE,PFA,F46 lined Diaphragm Valve have two types : weir (saddle) type and "straight-way" type .The weir type diaphragm valve has its two ports in line with each other on the opposite sides of the valve, whereas the weir type has the in/out ports located at a 90 degree angle from one another. The weir type is the most common in process applications and more commonly used as a tank bottom valve.
