SUN CKCBXCN Hydraulic Cartridge Valve (Pilot-Operated Check Valve)
The SUN Hydraulics CKCBXCN (CKCB-XCN) is a high-performance, pilot-operated check cartridge valve engineered for reliable load and pressure holding in demanding hydraulic applications. This valve allows free flow from the directional valve to the load while acting as a secure, leak-free check valve to block reverse flow. Reverse flow is only permitted when adequate pilot pressure is applied. Featuring a robust threaded slip-in cartridge construction with a hex installation head, radial flow ports at the nose section, and multiple O-ring body seals, the CKCBXCN ensures exceptional durability and zero-leak performance. It is specifically designed for critical load-holding circuits, making it an ideal choice for hydraulic cylinders, forklift clamps, and pile driver chucks.
