GPO Gas-over-Oil pipeline actuators
Blocking ball valves/plug valves in pipeline systems can be operated with a quarter-turn actuator using pipeline medium energy with pipeline pressure monitoring and safety shut-off features. Hydraulic hand pump and local controls are standard as well as oil tanks. The full control loop is high pressure so there is no need to install a pressure regulator in the control system. Optionally can be assembled with safety pressure reservoir, remote control solenoid valves, end position indicator, torque limiter, low-high pressure pilot valve, pneumatic or electronic line-break monitoring unit.
Output torque of the actuator can be used in the range of 590000 Nm (Double-acting) or 125000 Nm (Spring-return) between -60C … + 100C ambient temperature.
