The Danfoss CV2-20-P-0-5, part number 565844, is a high-performance, pilot-operated check valve designed for reliable operation in demanding hydraulic systems. This poppet-type cartridge valve allows free flow from the valve port to the cylinder port while preventing reverse flow. Flow is enabled in the reverse direction only when sufficient pilot pressure is applied. Engineered for durability and precision, it fits a standard size 20 (C-20-2) cavity, making it a versatile solution for load-holding applications, preventing cylinder creep, and isolating hydraulic circuits.
