The Hydraforce RV12-26A-0-N-35/25 (Material Number: 5623004.25) is a robust screw-in, cartridge-style, pilot-operated relief valve designed for demanding hydraulic circuits requiring fast response and low hysteresis. It is engineered as a pressure-limiting device that blocks flow from port 1 to port 2 until the pressure at port 1 reaches a level sufficient to activate the pilot relief, thereby allowing the main stage to open and redirect flow. This valve is not suitable for cross-over relief applications. Featuring hardened spool and cage components, it ensures long-lasting performance and offers optional spring ranges up to 240 bar (3500 psi) for versatile application needs. The RV12-26A-0-N-35/25 has a pressure rating of up to 241.3 bar (3500 psi) at port 1 and can withstand proof pressures of up to 689.5 bar (10000 psi). Its burst pressure capability reaches an impressive 1379.0 bar (20000 psi). The valve operates effectively with a maximum flow rating of 170.3 lpm (45 gpm) at maximum pressure and maintains internal leakage below 197 ml/min (12 in\u00b3/min) at port 2 under nominal settings. It supports operating fluid temperatures ranging from -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, accommodating various environmental conditions. Additionally, the valve can handle fluid viscosities between 7.4 to 420 cSt and supports mineral-based or synthetic fluids with lubricating properties. Installation requires a VC12-2 cavity with torque specifications between 44.7 to 50.2 N-m (33 to 37 ft-lb), ensuring secure mounting without orientation restrictions. The product includes corrosion protection tested for up to 960 hours in salt spray conditions per ASTM B117 standards, enhancing its durability in harsh environments.
