The Hydraforce PR12-36A-0-N-30/25 (5616912.25) is a spool type, pilot-operated hydraulic pressure reducing/relieving valve designed to regulate pressure in secondary circuits. This valve features an internal pilot and spring chamber drain, allowing 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 pressure. It can also relieve excess pressure from port 1 to port 3, with tank pressure being additive to regulated pressure. The PR12-36A model ensures adjustments cannot be backed out of the valve and prohibits springs from going solid, offering optional spring ranges up to 207 bar (3000 psi). It supports a maximum flow rating of 189.2 lpm (50 gpm) and maintains a proof pressure of up to 517.1 bar (7500 psi) across all ports, with a burst pressure capacity of 1034 bar (15000 psi). The valve operates efficiently within fluid temperatures ranging from -40 to 100 \u00b0C (-40 to 212 \u00b0F) when equipped with Buna N seals. It also meets corrosion protection standards with a rating of up to 960 hours in salt spray tests per ASTM B117. Designed for use with mineral-based or synthetic fluids possessing lubricating properties, it accommodates fluid viscosities between 7.4 and 420 cSt and maintains an operating contamination level of ISO 4406 cleanliness code of up to 18/16/13. The cartridge installation requires a torque range between 44.8 and 50.2 N-m (33 to 37 ft-lb), ensuring secure placement within VC12-3 cavities without any orientation restrictions.
