The Hydraforce CV08-21-0-N-30 (5200990) is a screw-in, cartridge-style hydraulic check valve designed for use as a blocking or load-holding device in hydraulic systems. This model allows fluid flow from port 2 to port 1 while normally blocking flow in the opposite direction. The valve features a fully guided check mechanism which is spring-biased closed, opening only when sufficient pressure is applied at port 2. It boasts a hardened seat for enhanced durability and minimal leakage, and its compact size facilitates easy integration into various system configurations. The CV08-21-0-N-30 is capable of handling pressures up to 3500 psi (241 bar) and operates efficiently across a wide range of temperatures depending on the seal material used: from -40 to +212°F with Buna N seals, -15 to +400°F with Fluorocarbon seals, and -65 to +225°F with Urethane seals. It supports fluid viscosities ranging from 7.4 to 420 cSt and tolerates a maximum operating contamination level as specified by ISO 4406 standards. This valve's design includes corrosion protection that withstands up to 960 hours of salt spray per ASTM B117, ensuring long-term reliability even in harsh environments. Its internal wetted surface area measures approximately 61.3 cm² (9.5 in²), and it weighs around 0.05 kg (0.12 lb). Installation specifications indicate it fits VC082 cavity configurations without orientation restrictions, and recommended installation torque ranges from 25.8 to 28.5 Nm (19 to 21 ft-lb). The CV08-21-0-N-30 also supports various seal kits for different environmental requirements, enhancing its adaptability across applications.
