The Hydraforce RV12-26B-0-N-35/ (Material Number: 5623104) is a screw-in, cartridge-style, pilot-operated (two-stage), spool-type relief valve. It is designed to serve as a pressure-limiting device in demanding hydraulic circuits that require rapid response and low hysteresis. The valve operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to move the pilot relief off its seat, which then shifts the main stage, allowing flow between the ports. Notably, this valve is not suitable for cross-over relief applications. Key features include adjustments that cannot be backed out of the valve, preventing springs from going solid, and a hardened spool and cage for enhanced longevity. The valve offers optional spring ranges up to 240 bar (3500 psi) and provides a smooth response to pressure surges. In terms of specifications, the RV12-26B-0-N-35/ has a pressure rating of up to 241.3 bar (3500 psi) at port 1 and 103.4 bar (1500 psi) at port 2. It can withstand proof pressures up to 689.5 bar (10000 psi) and burst pressures up to 1379.0 bar (20000 psi). The flow rating reaches up to 170.3 lpm (45 gpm) at maximum pressure with minimal internal leakage of 197 ml/min at port 2 under certain conditions. Temperature capabilities vary depending on seal materials: -40 to 100 \u00b0C with Buna N seals; -26 to 204 \u00b0C with fluorocarbon seals; and -54 to 107 \u00b0C with polyurethane seals. The unit has corrosion protection rated for up to 960 hours in salt spray per ASTM B117 standards and supports fluids ranging from mineral-based or synthetic with lubricating properties within a viscosity range of 7.4 to 420 cSt. Installation requires specific torque settings for optimal performance, ensuring reliability in various hydraulic applications.
