The Hydraforce RV10-26C-0-P-04 (5613205P) is a high-performance, screw-in, cartridge-style hydraulic relief valve designed for demanding hydraulic circuits requiring fast response and low hysteresis. This pilot-operated, two-stage spool-type valve effectively limits pressure by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to unseat the piloting relief. Once unseated, the main spool shifts to open the flow path between ports. The valve features non-backable adjustments with positive stops to prevent spring solidification, and it offers optional spring ranges up to 207 bar (3000 psi). It operates with a maximum pressure rating of 241 bar (3500 psi), proof pressure of 517.1 bar (7500 psi), and burst pressure of 1037.7 bar (15000 psi). The relief pressure can be defined at a flow rate of 7.57 lpm (2 gpm) and has a reseat pressure nominally at 90% of crack. It supports a flow rating of up to 113.6 lpm (30 gpm) at maximum pressure with internal leakage rated at different levels depending on the crack pressure setting. This valve accommodates various operating fluid temperatures based on seal material: -40 to 100 \u00b0C with Buna N seals, -26 to 204 \u00b0C with fluorocarbon seals, and -54 to 107 \u00b0C with polyurethane seals. It also has an ambient and storage temperature range from -40 to 70 \u00b0C. With corrosion protection lasting up to 960 hours in salt spray conditions per ASTM B117 standards, this valve is suitable for use with mineral-based or synthetic fluids within a viscosity range of 7.4 to 420 cSt. It fits into VC10-2 cavities and requires specific installation torques for both cartridge and adjuster cap components. Seal kits are available for maintenance purposes, providing versatility in various applications where precise hydraulic control is necessary.
