The Hydraforce RV10-28F-0-N-35/25.7 (5613703.25.7) is a versatile screw-in, cartridge-style, pilot-operated relief valve with a reverse free flow check valve. Designed for use in demanding hydraulic circuits, this product serves as a pressure-limiting device offering fast response and low hysteresis, leakage, and pressure override. It effectively blocks flow from port 1 to port 2 until the necessary pressure is reached at port 1, while allowing reverse flow from port 2 to port 1 when the pressure at port 2 exceeds that at port 1. The valve features various adjustment options that cannot be backed out of the valve and can operate in either relief or check valve mode with several available pressure ranges. Constructed with a hardened spool and cage for durability, it offers an industry-standard size and fast response time of 0.06 seconds from RV to CV at 241 bar (3500 psi) with a flow rate of 53 lpm (14 gpm). The maximum internal leakage is capped at 0.53 ml/min (10 drops/min), ensuring efficient operation even under high-pressure conditions up to its proof pressure of 620.5 bar (9000 psi) and burst pressure of 1241.1 bar (18000 psi). The adjustable pressure range spans from 13.8 to 289.6 bar (200 to 4200 psi), with the crack pressure defined as evident at a flow rate of 7.6 lpm (2 gpm). This relief valve operates efficiently across a wide temperature range depending on seal type: -40 to 100 \u00b0C with buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. It supports fluids that are mineral-based or synthetic with lubricating properties within a viscosity range of 7.4 to 420 cSt and maintains optimal performance under contamination levels up to ISO code18/16/13 per ISO4406 standards. Installation requires VC10-2 cavities with specific torque requirements for both cartridge installation and H style plug torque settings.
