The Sun Hydraulics RSHSLWV (RSHSLWV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This versatile valve controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. It can be used to regulate pressure in place of two-port relief valves when there is pressure in the return line. All three-port sequence cartridges from Sun Hydraulics are interchangeable, offering consistent flow paths and cavity compatibility for a given frame size. The main stage orifice in this model is protected by a 150-micron stainless steel screen, ensuring durability and reliability. The RSHSLWV is suitable for load-holding applications and features modulating that occurs inside the cartridge, making it resistant to issues like cavitation noise and manifold erosion. This valve can handle maximum pressure at port 2 and is ideal for cross-port relief circuits. Its construction minimizes internal part binding due to excessive installation torque or machining variations. Key specifications include a T-17A cavity, Series 3 capacity of 60 gpm (240 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 10 ms, and maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The adjustment allows for five clockwise turns to increase settings, with a valve hex size of 1-1/4 inches (31.8 mm) and an installation torque range of 150-160 lbf ft (203-217 Nm). The model weighs approximately 1.50 lb (0.70 kg) and includes a Viton seal kit for reliable performance in demanding conditions.
