Check Valves
The broad range of Vickers direct and pilot operated check valves provides the hydraulic circuit designer with a wide selection of cartridge and in-line products. Vickers check valve offering includes options for simple load holding devices, which serve as a low cost alternative to more complex solutions when overrunning loads are not present and/or control of load release speed is not required. Optional adjustable override releases the load for situations where pilot pressure is not always available. Product line includes 2-way check valves, bypass orifice, restrictive, single and double pilot operated, and double pilot check valves.
