The Hydraforce PR50-36C-0-P-30/ (5615207) is a high-performance spool type, pilot-operated hydraulic pressure reducing/relieving valve designed for precise pressure regulation in secondary circuits. Equipped with an internal pilot and spring chamber drain, it allows bidirectional flow from port 2 to port 1 in its steady state while maintaining continuous drainage at port 3. Upon reaching a set pressure at port 1, the spool shifts to limit inlet flow from port 2, thereby regulating the pressure. The valve can also relieve excess pressure from port 1 to port 3. Featuring hardened spools and cages for durability, it is available with optional spring ranges up to 345 bar (5000 psi). The PR50-36C-0-P-30/ accommodates a flow rating of up to 56.8 lpm (15 gpm) and withstands operating pressures of up to 344.7 bar (5000 psi) at ports 1 and 2, with a proof pressure of 482.6 bar (7000 psi) and burst pressure of 965.3 bar (14000 psi). It performs reliably across fluid temperatures ranging from -54 to 107 \u00b0C (-65 to 225 \u00b0F), depending on the seal material used, either polyurethane or urethane. This valve is corrosion-resistant withstanding up to 960 hours of salt spray as per ASTM B117 standards and fits into VC10-3 cavities requiring an installation torque between 44.7 to 50.2 N-m (33 to 37 ft-lb). It supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains optimal performance under contamination levels up to ISO code level of 20/18/14 per ISO4406 standards. Optional seal kits are available for maintenance purposes ensuring prolonged operational efficiency and reliability in demanding applications.
