Linear hydraulic valve actuators
Construction : Piston, TigeOperating pressure : Up to 20bars
Couples : Selon le besoin
Courses : Selon Ø de la vanne
Configuration : Double acting
Spring return
Materials : 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.
