QUARTER-TURN TYPE E-H ACTUATOR

AT30 series quarter-turn phneumatic-hydraulic actuator is suit for the bigger butterfly valve or ball valve need more torque,especially for petro-chemical and coal-chemical applications which need explosion proof type.

AT30 series P-H actuator is controled by positioner or solenoid,same as the phneumatic actuator.the difference is that it used integral hydraulic power-pack and cylinder,so it is smaller and higher cost performance than phneumatic actuator.
