Hydraulic actuators
GMI hydraulic actuators allow the remote automatic control of valves. The hydraulic oil network allows the opening and closing of valves.
Quarter-turn hydraulic valve actuators.
Construction : Scotch yoke actuatorsOperating pressure : Maxi 200bars
Torques : de 64 à 1000Nm
Configuration : Double acting
Spring return
Materials : Carbon steel, Stainless steel
High torque quarter-turn hydraulic valve actuators
Construction : Scotch yoke actuatorsOperating pressure : Maxi 350bars
Torques : Up to 400000Nm
Configuration : Double acting
Spring return
Materials : Cast iron, Carbon steel, Stainless steel
Linear hydraulic valve actuators
Construction : Piston / TigeOperating pressure : Up to 20bars
Configuration : Double acting
Spring return
Materias : Cast aluminium, Carbon steel, Stainless steel
Specific linear actuation solutions can be supplied for linear valves actuation:
-Globe valves
- Gate valve
- Knife-gates valves
- Diaphgram valves
-The design of hydraulic actuators for industrial valves: spring return or double acting .
-Linear or quarter-turn movement.
-Possible use of return springs.
-Default position: oil to close or oil to open.
-the oil or water network control pressure.
