DCV10 Lock Valve (DCV10)
An in-line-housed, double-pilot-operated, hydraulic check valve with optional thermal reliefs for use in blocking or load holding circuits.
Product Operation
The DCV10 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 at least 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 2 bar (30 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. Optional thermal reliefs are preset to 348 bar (5050 psi) as standard. NOTE: Thermal reliefs cannot be used with sealed pistons.
Product Features
• Hardened seat for long life and low leakage.• Check section serviceable as a cartridge.• Optional cartridge thermal relief(s).• Optional sealed piston. • Optional spring ranges.• Low pressure drop.
