The Hydraforce RV50-26H-0-P-50/35 (5613407.35) is a sophisticated screw-in, cartridge-style, pilot-operated hydraulic relief valve designed for high-demand hydraulic circuits. This two-stage spool-type valve functions as an effective pressure-limiting device, offering rapid response and minimal hysteresis. It operates by blocking flow from port 1 to port 2 until the pressure at port 1 is sufficient to activate the piloting relief, which then shifts the main spool to open the ports. Notably, this valve is not suitable for cross-over relief applications. Key features include adjustments that prevent spring solidification and cannot be backed out, along with a hardened spool and cage ensuring longevity and smooth pressure response. The RV50-26H-0-P-50/35 can handle a maximum pressure of 344.7 bar (5000 psi), with proof and burst pressures rated at 517.1 bar (7500 psi) and 1037.7 bar (15050 psi) respectively. Its flow rating reaches up to 113.6 lpm (30 gpm) at maximum pressure, with internal leakage capped at 147 ml/min at 85% of maximum crack pressure. The cycle life of this valve extends up to 500,000 cycles at a consistent pressure of 241.3 bar (3500 psi). Temperature resilience is notable; it operates efficiently within -40 to 100 \u00b0C using Buna N seals and has broader temperature ranges with other seal materials like fluorocarbon or polyurethane seals. Fluid compatibility includes mineral-based or synthetic options within a viscosity range of 7.4 to 420 cSt, maintaining optimal performance even under contamination levels specified by ISO standards. Installation requires adherence to specific torque values for both cartridge installation and H-style plug settings, ensuring secure fitting in VC10-2 cavities without orientation restrictions. The unit's weight varies slightly based on specifications but generally remains lightweight for ease of handling during installation or maintenance tasks.
