Hydraulic / Pneumatic Valve Actuator

详情

Product Overview:
Hydraulic/penumatic valve actuator is the valve actuator,using a fail-safe desigh(spring return),or by applying hydraulic pressure to open the valve,hydraulic or penumatic lost when the safety valve of the valve plate in promoting under the action of actuator spring,quickly lift,blocking the entire flow channel hole,so as to achieve the purpose of the safety valve closed.

Hydraulic valve actuators,the operating pressure is generally between ***0 ~ ****0PSI,can be equipped with diameter **1/*6 "**1",rated pressure ***0PSI ~ ****0PSI valve,the working medium of the hydraulic oil.
Pneumatic valve actuators,operating pressure generally less than **0PSI,working medium is compressed air,nitrogen, natural 
gas.  

Technical parameters:  

◆Oil / cylinder working pressure: ***0 ~ ****0PSI (pneumatic generally less than **0PSI);  

◆Operating temperature: **6 ~ **0 ℃.

Product Features:
◆quick connect bodies and body contact, easy to operate; ◆piston and cylinder can be removed from the top of the actuator does not need to touch the return spring;  

◆the actuator can switch the valve head pressure without the need to change the internal structure of the valve;

  Manually operated, pneumatically operated, pliers function, valve position indicator, failsafe on or off, the fire test, the open position locking devices.
