The Hydraforce RV16-26A-0-N-35/18 (Material Number: 5623503.18) is a high-performance, screw-in, cartridge-style relief valve designed for use in demanding hydraulic circuits that require 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, allowing the main spool to shift and open the flow path. With a pressure rating of up to 275.8 bar (4000 psi) and a proof pressure of 620.5 bar (9000 psi), it ensures robust performance under rigorous conditions. The valve boasts a burst pressure capacity of 1275.5 bar (18500 psi), making it suitable for high-pressure applications. The RV16-26A-0-N-35/18 features a flow rating of up to 302.8 lpm (80 gpm) at maximum pressure, with internal leakage rates varying based on the pressure setting: up to 114.7 ml/min at settings below 137.9 bar and up to 491.6 ml/min above this threshold when measured at port 2 at 85% of crack pressure. It operates effectively across a wide temperature range depending 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. This valve fits into VC16-2 cavities with an installation torque requirement between 62.7 and 73.4 N-m (46 to 54 ft-lb). It supports mineral-based or synthetic fluids with lubricating properties and maintains optimal performance within a fluid viscosity range of 7.4 to 420 cSt while adhering to an ISO contamination level of 18/16/13 for maximum operational efficiency.
