The Hydraforce PR50-38A-0-N-05 (Material Number: 5614900) is a screw-in, cartridge-style, direct-acting, spool-type hydraulic pressure reducing/relieving valve. This valve features an internal spring chamber drain and spool damping chamber, making it an effective pressure regulating device for secondary circuits. 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 reached at port 1, the valve shifts to block flow at port 2, thus regulating the pressure at port 1. Additionally, it can relieve excess pressure from port 1 to port 3 over the set reducing pressure. The PR50-38A-0-N-05 can handle a maximum pressure rating of up to 344.7 bar (5000 psi) for ports 1 and 2 and up to 68.9 bar (1000 psi) for port 3. It has a proof pressure of up to 482.6 bar (7000 psi) for ports 1 and 2 and a burst pressure capability of up to 1034 bar (15000 psi). This valve operates efficiently across various temperature ratings depending on the type of seals used: -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. It supports fluid viscosities ranging from 7.4 to 420 cSt and is designed for use with mineral-based or synthetic fluids possessing lubricating properties. The PR50-38A-0-N-05's rugged construction includes hardened spool and cage components that ensure long life and reliable performance under demanding conditions, making it suitable for applications requiring precise hydraulic pressure control in secondary circuits.
