Specifications

China pneumatic safety valves pressure reducing valve    

Description

Pressure relief valve QFY-300-type pressure relief valve is a pneumatic auxiliary unit. Would be reduced by the high-pressure compressed air pipe to the gas supply pressure pneumatic instrumentation required. Regulator and can play a role in high pressure valve output range of 0.005 ~ 0.4MPa is supporting the use of pneumatic actuators.
