The Hydraforce CV12-21-0-N-06 (5212000) is a screw-in, cartridge-style hydraulic check valve designed primarily for use as a blocking or load-holding device in hydraulic systems. This model facilitates flow from port 2 to port 1 while normally blocking flow in the opposite direction. The valve features a fully guided, spring-biased check mechanism that remains closed until enough pressure is applied at port 2 to initiate opening towards port 1. It boasts a hardened seat to ensure longevity and minimal leakage, enhancing its reliability in various applications. The CV12-21-0-N-06 is versatile, with optional bias springs available to adapt to different backpressure conditions, making it suitable for diverse operational demands. Its design minimizes check mass to reduce cavitation risks, crucial for maintaining system integrity under fluctuating pressures. This model operates efficiently within a pressure rating of up to 240 bar (3500 psi) and exhibits maximum internal leakage of only five drops per minute at this pressure level. Temperature adaptability is another strong feature of this valve, with operational fluid temperatures ranging from -40°C to +100°C using Buna N seals, and even wider ranges possible with other seal materials like fluorocarbon and polyurethane. The CV12-21-0-N-06 supports a broad fluid viscosity range from 7.4 to 420 cSt and maintains performance within maximum operating contamination levels specified by ISO 4406 standards. Installation specifications include a VC122 cavity requirement and an installation torque ranging between 44.7 to 50.2 Nm (33 to 37 ft-lb), with no orientation restrictions noted, providing flexibility in system design. This model's unit weight stands at approximately 0.16 kg (0.37 lb), contributing to its ease of integration into existing systems without significant modifications.
