The Hydraforce PR12-36A-0-N-30/ (5616912) is a spool-type, pilot-operated hydraulic pressure reducing/relieving valve designed to regulate pressure in secondary circuits. This valve allows bidirectional flow from port 2 to port 1 while maintaining a constant drain at port 3. When the predetermined pressure at port 1 is reached, the spool shifts to restrict inlet flow from port 2, thereby regulating the pressure at port 1 and relieving any excess pressure to port 3. Notably, this valve features adjustments that cannot be backed out and prevents springs from going solid, with optional spring ranges up to 207 bar (3000 psi). The PR12-36A model supports a maximum flow rating of 189.2 lpm (50 gpm) and can handle pressures up to 241.3 bar (3500 psi) at ports 1 and 2, with a lower rating of 103.4 bar (1500 psi) at port 3. It boasts an impressive proof pressure of 517.1 bar (7500 psi) across all ports and a burst pressure of up to 1034 bar (15000 psi). Designed for durability, it offers corrosion protection for up to 960 hours in salt spray per ASTM B117 standards. The valve operates efficiently within fluid viscosity ranges of 7.4 to 420 cSt and maintains optimal performance under operating fluid temperatures from -40\u00b0C to +100\u00b0C with Buna N seals. The cartridge installation requires a torque range between 44.8 and 50.2 N-m (33 to 37 ft-lb), fitting into VC12-3 cavities without orientation restrictions. With an internal wetted surface area of up to 279 cm\u00b2 for certain models, the PR12-36A is a robust component suitable for various hydraulic applications where precise pressure control is essential.
