Sun Hydraulics Check Valve # CKCB-XCN

Technical Features
This 3 port pilot-to-open check valve and 3 port counterbalance valves are physically interchangeable (i.e. same cavities, same flow path for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
Pilot-to-open check cartridges are locking valves, not motion control valves. For motion control applications, use counterbalance valves.
Provides hose break protection, prevents loads from drifting and positively locks pressurized loads.
For models with manual load release control option, turn load release clockwise to release load.
Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit.
Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP (see Option Selection below). External parts are made from stainless steel with titanium or brass components, where applicable. Internal parts are made from carbon steel leaded alloy, the same as standard valves. For further details, please see the Materials of Construction page.
Extremely low leakage. The seat and poppet are heat treated for long life. If the load drifts due to the valve, the seat has probably been damaged by contamination and the valve should be replaced.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
Optional external porting out of the hex end of the cartridge is available for external piloting. In this configuration, port 3 is blocked. See Control options E, and P.
