The Hydraforce RV12-26H-0-N-04 (Material Number: 5623400) is a robust, screw-in, cartridge-style pilot-operated relief valve designed for high-performance hydraulic systems. This two-stage spool-type valve serves as a pressure limiting device, ensuring optimal flow control and system protection in demanding applications. The RV12-26H-0-N-04 effectively blocks flow from port 1 to port 2 until the pressure at port 1 reaches the threshold to activate the pilot relief, allowing the main stage to shift and open flow between the ports. It is important to note that this valve is not suitable for cross-over relief applications. The valve features hardened spools and cages for enhanced durability and longevity. It offers optional spring ranges up to 240 bar (3500 psi), providing rapid and smooth responses to pressure surges. The RV12-26H model has a maximum flow rating of 170.3 liters per minute (45 gallons per minute) at maximum pressure, with an internal leakage rate of 197 ml/min (12 in\u00b3/min) at port 2 when set at 85% of its nominal setting. This relief valve operates efficiently across a wide range of fluid temperatures, depending on the seal material used: -40 to 100 \u00b0C (-40 to 212 \u00b0F) with Buna N seals, -26 to 204 \u00b0C (-15 to 400 \u00b0F) with fluorocarbon seals, and -54 to 107 \u00b0C (-65 to 225 \u00b0F) with polyurethane seals. It is designed for use with mineral-based or synthetic fluids possessing lubricating properties and can handle fluid viscosities ranging from 7.4 to 420 cSt. The RV12-26H's installation specifications include compatibility with VC12-2 cavities and a cartridge installation torque requirement between 44.7 and 50.2 N-m (33 to 37 ft-lb). Additionally, it boasts corrosion protection up to 960 hours in salt spray conditions according to ASTM B117 standards.
