The Hydraforce PR50-38A-0-N-05/03.6 (Material Number: 5614900.03.6) is a screw-in, cartridge-style, direct-acting spool type hydraulic pressure reducing/relieving valve. It features an internal spring chamber drain and spool damping chamber, making it ideal for regulating pressure in secondary circuits. The valve allows bidirectional flow from port 2 to port 1 in its steady state, while the spring chamber is continuously drained at port 3. When a predetermined pressure is reached at port 1, the valve shifts to block flow at port 2 to regulate pressure at port 1 and relieve excess pressure from port 1 to port 3. This model includes a hardened spool and cage for durability and offers optional spring ranges up to 227.5 bar (3300 psi). The PR50-38A can handle pressures up to 344.7 bar (5000 psi) for ports 1 and 2, with a lower rating of 68.9 bar (1000 psi) for port 3, ensuring robust performance under demanding conditions. The proof pressures are rated at 482.6 bar (7000 psi) for ports 1 and 2, while burst pressure reaches up to an impressive 1034 bar (15000 psi), providing significant safety margins during operation. It operates effectively across a wide temperature range depending on the seal material used: -40 to +100 \u00b0C with Buna N seals, -26 to +204 \u00b0C with fluorocarbon seals, and -54 to +107 \u00b0C with polyurethane seals. Designed for use with mineral-based or synthetic fluids that have lubricating properties, this valve supports fluid viscosities ranging from 7.4 to 420 cSt and maintains maximum operating contamination levels of ISO class 20/18/14. Additionally, it has an internal wetted surface area of either 215 cm\u00b2 or195 cm\u00b2 depending on configuration and requires specific installation torques for optimal performance in VC10-3 cavities without orientation restrictions.
