The Hydraforce RV50-26A-0-P-50 (5613002) is a high-performance, screw-in, cartridge-style, pilot-operated spool type hydraulic relief valve. Engineered as a pressure-limiting device for demanding hydraulic circuits, this valve is renowned for its rapid response and low hysteresis. It effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to activate the piloting relief, thereby shifting the main spool and allowing flow between ports. Notably, this valve is not suitable for cross-over relief applications. Key features include non-backable adjustments that prevent springs from going solid and a hardened spool and cage for extended durability. The RV50-26A-0-P-50 operates within a pressure range of 20.7 to 344.7 bar (300 to 5000 psi) and has proof and burst pressures of 517.1 bar (7500 psi) and 1037.7 bar (15050 psi), respectively. With a flow rating of up to 113.6 lpm (30 gpm) at maximum pressure and an internal leakage rate of up to 147 ml/min at 85% of maximum crack pressure, this valve ensures efficient operation under high-pressure conditions. The valve's cycle life is rated at 500,000 cycles at a pressure of 241.3 bar (3500 psi). It operates across various temperature ranges depending on the seal material used: -40 to 100 \u00b0C with Buna N seals; -26 to 204 \u00b0C with fluorocarbon seals; -54 to 107 \u00b0C with polyurethane or urethane seals. The RV50-26A-0-P-50 fits into VC10-2 cavities and requires an installation torque between 47.6 to 50.2 N-m, with a maximum allowable torque of up to 67.8 N-m. The unit weighs between approximately 0.24 kg to 0.29 kg depending on configuration and has an internal wetted surface area ranging from about 141 cm\u00b2 to161 cm\u00b2 based on model specifics.
