Contact usDCV08 Lock Valve (DCV08)
An in-line-housed, double-pilot-operated, hydraulic check valve for use in blocking or load holding circuits.
Product Operation
The DCV08 allows flow from V ports to C ports, while normally blocking flow in the opposite direction. Flow will be allowed from C to V when pressure is applied to the opposite side V port.
The valve has a 4:1 pilot ratio, so approximately one-fourth of the load pressure held at either C port is required at the opposite V port to open the flow passage.
The check is spring-biased at 1.7 bar (25 psi) to assure holding in static or no-load conditions. An optional sealed piston with check spring bias of 6.9 bar (100 psi) is available.
Product Features
• Hardened seat for long life and low leakage.• Check section serviceable as a cartridge.• Optional sealed piston.• Optional spring ranges.• Low pressure drop.
