Pneumatic hydraulic actuator

Product Details

Name: Pneumatic hydraulic actuator



GH and GHL series pneumatic hydraulic valve actuators use high pressure process gas to provide power for valve actuators and automate valves. In order to improve safety and reliability, the process gas acts on the hydraulic oil stored in the air and oil cylinder to generate hydraulic pressure, which is then used to drive the hydraulic valve actuator. As a standard, high-pressure process gas or hydraulic manual pump is used in the gas and oil control system to provide local opening and closing control. There are many additional control systems to choose from; It includes line break detection (drop rate and high/low) and remote control.



Scope of application:


Automation of rotary valve and linear valve for gas transmission pipeline.


Operating range:


Supply pressure:


13 to 250 (90 to 3625 psig)


Torque and thrust output:


GH - Series: 200 - 680nm (1770 - 6018000 lbs)

GHL - Series: up to 289134 N (65000 lbf)


Main features and advantages:


Low or high voltage control system design.

Suitable for operation of acid and wet power gas.

Compact and highly reliable parallel control system.

The manifold of modular control systems allows rapid, simple, and inexpensive control of changes or services to system functions.

Fully enclosed control lock cover provides excellent environmental protection and unauthorized operation protection

Hydraulic manual override, as a standard, allows local opening and closing of valves to reduce the supply of power gas.

The power gas is used as the standard local open close valve control.

Speed control for independent opening and closing of valves is standard.

Oil, gas and power gas storage tanks approved by PED or ASME are used to control power gas safely.

The valve actuator has a symmetrical, inclined, and demi canted design that ensures optimal actuator classification and Lloyd's certified operation to - 65 ° C (- 85 ° F).

Linear valve actuator system.

Double acting and spring return actuator configuration.

Certification of valve actuators, ip66 m.

The valve actuator is approved by the third party for SIL 3 application.

The valve actuator is certified according to PED 93/27/EC.
