Safety relief valve

  • Low lift Spring-Loaded pressure Safety relief Valve
    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 medium's 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 spring force, disc sealing faces and valve seat sealed again, the valves close automatically.
  • A46C Pilot operated safety relief valve
    Pilot operated safety relief valve,newly -structure,is mainly applied to such trades as petroleum&natural gas,Chemistry,electric,metallurgy&burning gas.It is the best super-pressure protecting equipment on press equipment,Container,or pipeline.It is mainly characterized by shifting direct function of spring to indirect function of guide valve,What's more,main valve,applying for sleeve piston&double sealed seat,It is characterized by high precision of action,good recycling function,fast turning back to seat,ability to high-pressure leaking,long working time&security,together with read-adjustment on line,automatic turning back to seat after leaking again and again,tight closure,operating and maintaining convenience.
  • Brass Safety Relief Valve
    Brass safety relief valve(A48Y) are used for the equipment and pipeline of the seatm and air medium etc.the working temperature are less than 350℃,Take for extra pressure protection devices.Flange connectiong dimensions of cpmply with standard of JB/T79.1-94,when the pressure less than 4.0Mpa,comply with standard series two of JB/T79.2-94 when more than 4.0Mpa.It can be used in different production fields and various activities as compressed air, technical gases, fluids, chemical industries, pharmaceutical industries, food industries and water treatment.
  • 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. This valve’s type include A48C Open Bonnet Plain Lever Safety Valve,A48Y High Temperature and High Pressure With Radiator Safety Valve,High Performance Steam Safety Valve which meets the requirement of ASME secⅠ,High Temperature High Pressure Welded Safety Valve.
  • Thermal threaded pressure low lift safety relief valve
    Direct Spring Operated Pressure Relief Valve(PRV) or Safety Valve is the best on the pressure equipment, container and pipeline over pressure protection device. Flanged Pressure Relief 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.This valve’s type include A42H Conventional Safety Valve, WA42C Balance Bellows Safety Valve, A44H Packed Lever Safety Valve, A48H Open Bonnet Plain Lever Type Safety Valve, WA44H Packed Lever Balance Bellows Safety Valve etc.
