QUARTER-TURN TYPE E-H ACTUATOR

      AT31 series actuator can use for the linear type valve such as gate and globe valve.compare to the phneumatic actuator, AT30 is smaller and faster.
Same as the quarter-turn type,AT30 have two types:1)ON/OFF(MODE ‘E’), 2)Modulating(MODE‘M’)。

  AT31 Linear Type Phneumatic-Hydraulic actuator

FEATURES

●  Smaller,Low cost, Easy maintenance

●  Phneumatic control,Hydraulic drive.

●  Hydraulic oil compressed little,so AT30 control characteristic better and accuracy higher.

●  Intrinsic-safe avalible.

●  Easy installation and easy maintenance.

●  Higher cost performance.

●  Controled by solenoid or positioner
