The Hydraforce PR50-38A-0-N-05/05 (5614900.05) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve designed for secondary circuit applications. This direct-acting, spool-type valve features an internal spring chamber drain and spool damping chamber, ensuring consistent performance and longevity. It allows bidirectional flow from port 2 to port 1 in its steady state while maintaining constant drainage at port 3. When a predetermined pressure is achieved at port 1, the valve shifts to block flow at port 2, effectively regulating the pressure at port 1. Additionally, the valve can relieve pressure from port 1 to port 3 over a variable value above the set reducing pressure. The PR50-38A-0-N-05/05 is built with hardened spool and cage components for extended durability and features optional spring ranges up to 227.5 bar (3300 psi). It cannot be adjusted beyond its operational limits, preventing springs from becoming solid. With a maximum pressure rating of 344.7 bar (5000 psi) for ports 1 and 2 and a proof pressure of up to 482.6 bar (7000 psi), this valve is robust enough for demanding applications. Temperature ratings vary based on seal material: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. The unit weighs between 0.26 kg and 0.31 kg depending on configuration and has an internal wetted surface area of either 215 cm\u00b2 or 195 cm\u00b2. The cartridge fits into VC10-3 cavities with installation torques ranging from 33.9 to a maximum of 67.8 N-m, ensuring secure placement without orientation restrictions. The product also offers corrosion protection withstanding up to a 960-hour salt spray test per ASTM B117 standards, making it suitable for various environmental conditions.
