The Hydraforce PR12-36C-0-N-15/ (5616924) is a spool type, pilot-operated hydraulic pressure reducing/relieving valve designed for secondary circuit pressure regulation. It allows bidirectional flow from port 2 to port 1 while maintaining a constant spring chamber drain at port 3. When a specific pressure is reached at port 1, the spool shifts to regulate inlet flow from port 2 and relieve excess pressure from port 1 to port 3. The valve features adjustments that prevent springs from going solid and offers optional spring ranges up to 207 bar (3000 psi). It has a pressure rating of up to 241.3 bar (3500 psi) at ports 1 and 2, with proof and burst pressures of 517.1 bar (7500 psi) and 1034 bar (15000 psi), respectively. The maximum flow rating is 189.2 lpm (50 gpm), with a maximum pilot flow of 0.170 lpm (0.045 gpm) under specified conditions. Temperature ratings include an operating fluid temperature range of -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, storage temperature range of -40 to 70 \u00b0C (-40 to 160 \u00b0F), and ambient temperature range of -40 to 70 \u00b0C (-40 to 160 \u00b0F). Corrosion protection meets a standard of up to 960 hours salt spray per ASTM B117. Suitable for use with mineral-based or synthetic fluids with lubricating properties, it supports fluid viscosity ranges from 7.4 to 420 cSt and maintains cleanliness levels per ISO standards. The unit weighs approximately between .45 kg (.99 lb) for the PR12-36C/L model, features an internal wetted surface area of about .260 cm\u00b2 (.403 in\u00b2), installs in VC12-3 cavities requiring torque specifications between .44.8 and .50.2 N-m (33 to .37 ft-lb), and has no orientation restrictions for installation. Accessories include seal kits like SK12-3X-BM with installation instructions available for various seal options.
