Pilot Operated Pressure Safety Valve

Pilot-operated safety valve is a safety valve of a novel structure . Mainly used for oil and gas,
chemical, power, metallurgy and other fields of city gas, overpressure protection device is the
best compression equipment, containers or tubes on the road. Its main advantage is the direct effec
t of varying the pilot valve spring indirect role in enhancing the sensitivity of the action, and
the use of the main valve piston sleeve, high motion accuracy, repeatabity, high- back seat
pressure, good sealing performance, high-energy band back pressure discharge, stable and reliable,
available online adjustment, easy operation and maintenance
