The Hydraforce PR12-36B-0-N-30/ (Material Number: 5616913) is a spool type, pilot-operated hydraulic pressure reducing/relieving valve. This model is engineered to regulate pressure in secondary circuits with an internal pilot and spring chamber drain. In its standard operation, the valve allows bidirectional flow from port 2 to port 1, with continuous drainage at port 3. When a set pressure at port 1 is reached, the spool shifts to restrict flow from port 2, thereby regulating the pressure at port 1 and relieving excess pressure to port 3. The PR12-36B features adjustments that prevent springs from going solid and offers optional spring ranges up to 207 bar (3000 psi). It boasts a maximum pressure rating of 241.3 bar (3500 psi) for ports 1 and 2, while port 3 can handle up to 103.4 bar (1500 psi). The proof and burst pressures are rated at an impressive 517.1 bar (7500 psi) and 1034 bar (15000 psi), respectively. The valve supports a flow rating of up to 189.2 lpm (50 gpm) and a maximum pilot flow of 0.170 lpm (0.045 gpm) under specific conditions. It operates efficiently within fluid temperatures ranging from -40 to 100\u00b0C (-40 to 212\u00b0F), making it suitable for various environmental conditions with buna N seals. The unit's corrosion resistance is tested for up to 960 hours in salt spray per ASTM B117 standards. Designed for compatibility with mineral-based or synthetic fluids, the PR12-36B accommodates fluid viscosities between 7.4 to 420 cSt and maintains an operating contamination level of ISO class cleanliness standards. The unit weighs approximately 0.43 kg (0.94 lb) and fits into VC12-3 cavities, requiring specific installation torques for optimal performance without orientation restrictions.
