3 way converging-diverging control valve

3 way converging/diverging control valve adopts the cage guided structure and pressure unbalanced plug. It is mainly used for converging or diverging media of several flow channels. Entering from two channels and exiting from one channel is called three-way converging, and conversely, entering from one channel and exiting from two channels is called diverging. The three-way valve can also play the pipe shut-off and opening function. The standard converging/diverging design is the unbalanced doubl…

Electric Straight Through control valve

Electric Straight Through control valve is actuating unit of electrical unit combined apparatus. It receives direct current signal from regulating apparatus and change flow of mediums directly (e.g. liquid, gas, steam, etc.) to keep controlled technological parameters (e.g. temperature, pressure, flow, liquid level, etc.) at setting values. Electric Straight Through control valve is PS series or 3810L series straight stroke electric actuator and low flow resistance through single seat valve. (can…

Spring Loaded Steam Safety Relief Valve

Spring Loaded Steam Safety Relief Valve is used in power plant boilers,pressure containers and temperature reducing devices and other facilities.It serves to prevent pressure from exceeding max. allowed value and ensure the safety of the device during working.Steam Safety Valve sizing and selection acc.to API 520(ASME secⅧ),designed acc.to API 526,test acc.to API 527(ASME PTC 25),flange acc.to ASME B16.5.

Spring Loaded Safety Relief Valve For Liquid

Spring-loaded safety relief valve works through adjusting spring force to prevent medium pressure and realize sealing purpose. Under the condition of spring force greater than mediums normal pressure, valve disc is at the close state, when medium pressure exceeds the set pressure, the spring is compressed, and lead the disc sealing faces separated, the valve open automatically, and relief pressure; When medium pressure reduced to normal pressure, the valve disc go back to valve seat under the spr…
