The Hydraforce HCV06-20-0-U-05 (5500200) is a screw-in, cartridge-style hydraulic check valve designed for high-pressure applications primarily used as a blocking or load-holding device. This model allows fluid flow from port 1 to port 2 and blocks the flow in the reverse direction. The valve features a fully guided poppet that is spring-biased closed, requiring sufficient pressure at port 1 to open towards port 2. Constructed with a hardened seat, the HCV06-20-0-U-05 ensures long life and minimal leakage. It adheres to NFPA specification T2.6.1 standards, with rigorous testing that includes a verification level of 90 and an assurance level of 99. The valve can handle up to 350 bar (5075 psi) operating pressure and has proof pressures up to 690 bar (10000 psi), with burst pressures reaching 1380 bar (20000 psi). The maximum flow rate for this unit is approximately 19 liters per minute (5 gallons per minute), and it exhibits exceptionally low internal leakage of about 0.10 ml/min at maximum operating pressure, ensuring efficient operation. It supports various seal materials suitable for different temperature ranges—Buna N seals operate between -40°C to +100°C, Fluorocarbon seals from -26°C to +204°C, and Urethane seals from -54°C to +107°C. This model is versatile in its installation options with no orientation restrictions and fits in a standard HVC062 cavity; recommended installation torque is between 26 to 28 Nm for steel or ductile iron cavities. Additionally, various seal kits like SK062NT (Buna N), SK062VT (Fluorocarbon), and SK062UO (Urethane) are available, ensuring maintenance flexibility across different system requirements. This makes the Hydraforce HCV06-20-0-U-05 an ideal choice for robust hydraulic systems requiring reliable backflow prevention.
