The Hydraforce PR50-36H-0-P-50/21 (Material Number: 5615408.21) is a spool-type, pilot-operated hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. This valve features an internal pilot and spring chamber drain, allowing bidirectional flow from port 2 to port 1 in a steady state, with the spring chamber continuously drained at port 3. When the pressure at port 1 reaches a predetermined level, the spool shifts to restrict inlet flow from port 2, effectively regulating pressure at port 1 and relieving it to port 3 if necessary. The PR50-36H model is equipped with hardened spools and cages for enhanced durability and offers optional spring ranges up to 345 bar (5000 psi). It is compatible with mineral-based or synthetic hydraulic fluids within a viscosity range of 7.4 to 420 cSt and operates effectively under fluid temperatures ranging from -54\u00b0C to 107\u00b0C (-65\u00b0F to 225\u00b0F). The valve can withstand pressures up to a proof rating of 482.6 bar (7000 psi) and burst pressures of up to 965.3 bar (14000 psi). With a flow rating of up to 56.8 lpm (15 gpm) and maximum pilot flow of 0.170 lpm (0.045 gpm), it ensures reliable performance in demanding applications. The PR50-36H model weighs approximately 0.25 kg (0.55 lb) and fits into VC10-3 cavities with installation torques ranging between 44.7 to 50.2 N-m (33 to 37 ft-lb). It also meets ASTM B117 standards with corrosion protection for up to 960 hours in salt spray conditions, ensuring long-lasting performance even in harsh environments.
