The Hydraforce PR50-38A-0-P-15/ (5614911P) is a screw-in, cartridge-style hydraulic pressure reducing/relieving valve. This direct-acting, spool-type valve features an internal spring chamber drain and spool damping chamber, making it ideal for pressure regulation in secondary circuits. In its steady state, it allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. Once a predetermined pressure is reached at port 1, the valve shifts to block flow at port 2, thus regulating the pressure. It can also relieve excess pressure from port 1 to port 3 over the set reducing pressure. The valve's design includes hardened spools and cages for durability and optional spring ranges up to 227.5 bar (3300 psi). It has a maximum pressure rating of 344.7 bar (5000 psi) for ports 1 and 2, with proof pressures reaching up to 482.6 bar (7000 psi). Port 3 has a lower maximum pressure rating of 68.9 bar (1000 psi). The burst pressure of the valve is an impressive 1034 bar (15000 psi). It operates efficiently across various temperature ranges depending 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 and urethane seals. The PR50-38A-0-P-15/ can handle fluid viscosities ranging from 7.4 to 420 cSt and requires mineral-based or synthetic fluids with lubricating properties for optimal performance. Its corrosion resistance is tested up to a remarkable 960 hours in salt spray conditions per ASTM B117 standards. Installation requires specific torques depending on the component: cartridge installation torque ranges between 33.9 to 36.6 N-m or up to a maximum of 67.8 N-m for certain applications, while H style plug torque ranges between 10.8 to13.6 N-m.
