Pneumatic Hydraulic Actuators for Shut-off Valves DN 050-1400 - Remote and Local Control

Pneumohydraulic actuators are designed for remote and local control of shut-off pipeline quarter-turn valves, as well as signalling the valve gate position to the control panel. Control medium parameters: non-aggressive natural gas, temperature from - 60 °? to +80 °?.

Control signal voltage - 24 V or 110 V. Pump handle force - up to 250 N. Damping liquid PMS-20 Yugra (analogues in the register of PJSC Gazprom can be used).

They are manufactured in seismic-resistant version for areas with seismicity up to 9 points on MSK-64 scale. Ball valves with pneumohydraulic actuators DN 150 - 500 mm are completed with control units Other assemblies, control units and end position indicators are available. If the pneumohydraulic actuator is equipped with the control unit BUK-2, it is possible to realise the functions "normally open" or "normally closed".

Pneumohydraulic actuators can be equipped with automatic emergency valve closure (AAZK).
