Hydraulic On / Off Valves
Hydraulic actuation is very cost effective when hydraulic pressure is already available, where valves must shut off against high operating pressures and for valves larger than 10” when operating pressures exceed 90 psi (6 bar). Approximately 2/3 smaller in size and weight than other actuators, hydraulic actuators reduce the amount of support infrastructure required and facilitate installation when space constraints are a concern.
Typical applications for hydraulic on-off valves are filter press feed valves, ash sluice valves, tailings slurry valves, high pressure slurry valves, or for dense-phase pneumatic transport, such as cement powder valves.
Accessories and Options:
- Manual hydraulic pump actuation
- Solenoid Valves
- Open/Close Limit Switches
- Proximity switches
- Pressure Regulators
- Protective Guards
Air actuated hydraulic pump
Where operating conditions require hydraulic actuation but only plant air is available, valves are supplied with a pneumatically operated hydraulic pump capable of operating one or more valves from the same pumping station.
