Pneumatic and hydraulic actuator valves

We designed a number of gate valves equipped with hydraulic and pneumatic actuators.

The gate valves automatically open when the pressure in the actuator drops and close when the actuator control pressure is on.

Pneumatic actuator working medium is nitrogen, dried and purified natural gas or air. Control pressure is 2.5 MPa.

Hydraulic actuator working medium is glycol. Control pressure is 9…21MPa.

The design of the actuated valves allows to remove the actuator and to replace the stem packing when the pressure in the line is on.

The repair of the actuators can be made separately without disassembling of the gate valve.

There are sensors which monitor “open” and “close” positions.

The design of the actuator allows to use it as double-function actuator in the gate valves with balancing stem.
