The Hydraforce CV04-20-0-N-05 (5191000) is a screw-in, cartridge-style hydraulic check valve designed for use as a blocking or load-holding device in hydraulic systems. This model facilitates fluid flow from port 1 to port 2 while normally preventing flow in the reverse direction. It features a fully guided check mechanism, which remains spring-biased closed until sufficient pressure at port 1 compels it to open towards port 2. The valve boasts a pressure rating of up to 241 bar (3500 psi) and supports a flow rate of 7.6 liters per minute (2 gallons per minute). It demonstrates exceptional leakage control, with maximum internal leakage maintained at approximately 0.10 ml/min (2 drops/min) under maximum pressure conditions. The CV04-20-0-N-05 can operate effectively within a fluid temperature range of -40°C to +100°C with Buna N seals, -26°C to +204°C with fluorocarbon seals, and -54°C to +107°C with polyurethane seals. Additional specifications include a corrosion resistance of up to 960 hours in salt spray per ASTM B117, making it highly durable under harsh conditions. The valve is compatible with mineral-based or synthetic hydraulic fluids with lubricating properties and can handle fluid viscosities ranging from 7.4 to 420 cSt. Its design ensures that it can function within an ambient temperature range of -40°C to +90°C and be stored between -40°C to +70°C without compromising its integrity. Installation features such as the VC042 cavity specification and cartridge installation torque requirements between 16.3 and 19.0 Nm ensure ease of integration into existing systems without orientation restrictions. The unit's lightweight design at just 0.01 kg (0.03 lb) facilitates easy handling and installation, further complemented by available accessories like the SK042XT seal kit for maintenance and repair needs.
