The Sun Hydraulics RSHCLEN (RSHCLEN) is a pilot-operated, balanced piston sequence valve designed to efficiently manage secondary circuit flow once the inlet port pressure surpasses the valve's set threshold. This valve is engineered to control pressure at port 1 relative to the drain port 3 pressure, remaining unaffected by back pressure at port 2 up to the valve setting. It can substitute for two-port relief valves when there's pressure in the return line. Notably, all three-port sequence cartridges are interchangeable in terms of flow path and cavity for a specific frame size. The valve features a main stage orifice shielded by a 150-micron stainless steel screen and can handle pressures at port 3 up to 5000 psi (350 bar), directly affecting the valve setting at a 1:1 ratio. However, it isn't suitable for load-holding applications due to spool leakage. The RSHCLEN model incorporates Sun's floating style construction, reducing internal binding risks from installation torque or machining variations. It has a Cavity T-17A Series 3 with a capacity of 60 gpm (240 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with typical response times around 10 ms. Maximum valve leakage is specified at four in\u00b3/min (65 cc/min) under conditions of 110 SUS (24 cSt) fluid viscosity and pressures up to 1000 psi (70 bar). The adjustment mechanism allows for five clockwise turns to increase settings, with installation torque requirements between 150-160 lbf\u00b7ft (203-217 Nm). The model includes Viton seals and weighs approximately 1.50 lb (0.70 kg).
