The Hydraforce RV12-26A-0-V-35/26 (Material Number: 5623005.26) is a screw-in, cartridge-style, pilot-operated (two-stage), spool-type relief valve designed for use as a pressure-limiting device in demanding hydraulic circuits requiring fast response and low hysteresis. This valve effectively blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to activate the pilot relief, allowing the main stage to open and permit flow between the ports. It is important to note that this valve is not suitable for cross-over relief applications. Key features include non-backable adjustments that prevent springs from going solid, a hardened spool and cage for extended life, and optional spring ranges up to 240 bar (3500 psi). The RV12-26A offers rapid and smooth responses to pressure surges within its cost-effective cavity design. The valve's pressure ratings are set at 241.3 bar (3500 psi) for port 1 and 103.4 bar (1500 psi) for port 2, with proof and burst pressures at an impressive 689.5 bar (10000 psi) and 1379.0 bar (20000 psi), respectively. Its flow rating reaches up to 170.3 lpm (45 gpm) at maximum pressure, with internal leakage capped at 197 ml/min at port 2 when operating at 85% of its nominal setting. Temperature ratings vary 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. The RV12-26A also offers robust corrosion protection of up to 960 hours in salt spray conditions per ASTM B117 standards. It accommodates mineral-based or synthetic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and requires a maximum operating contamination level of ISO code cleanliness of up to ISO4406:18/16/13 for optimal performance.
