Description Material Performance Product Size Specifications

Oil refining safety valve is one of the accessories of petrochemical pressure vessel, which is used to control air pressure and ensure container safety. This series of safety valve is closed fully open spring safety valve, that is, when the gas medium pressure is higher than the set pressure 3%, the valve opening height exceeds the flow channel diameter of 1/4. This series of safety valve can be used in stable pressure, no corrosion or slight sulfur corrosion of gas, liquid.
Note: parameters for reference only, or not. Valve can be selected according to the requirements of different pressure, material, caliber, drive, etc.. Specific please call or online advice.
