The Hydraforce PR12-36A-0-N-30/27.5 (Material Number: 5616912.27.5) is a spool-type, pilot-operated hydraulic pressure reducing and relieving valve. This component is designed to regulate pressure in secondary circuits, ensuring optimal performance and safety in hydraulic systems. It 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 regulate inlet flow from port 2, effectively controlling the pressure at port 1 and relieving excess pressure from port 1 to port 3. The valve can handle pressure ratings up to 241.3 bar (3500 psi) for ports 1 and 2, with a lower rating of 103.4 bar (1500 psi) for port 3. It boasts a proof pressure of up to 517.1 bar (7500 psi) across all ports and a burst pressure of an impressive 1034 bar (15000 psi). The flow rating stands at a maximum of 189.2 liters per minute (50 gallons per minute), with maximum pilot flow reaching up to 0.170 liters per minute under specific conditions. Temperature ratings for operation range from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, ensuring functionality in diverse environments. The valve also offers significant corrosion protection withstanding up to 960 hours of salt spray as per ASTM B117 standards. This model requires installation in VC12-3 cavities and should be torqued between 44.8 to 50.2 N-m (33 to 37 ft-lb). With its robust design and precise control capabilities, the PR12-36A-0-N-30/27.5 is well-suited for applications requiring reliable pressure regulation within hydraulic systems.
