The Sun Hydraulics RSHCLAN (RSHCLAN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This sequence valve manages pressure at port 1 relative to the pressure at the drain port 3 and remains unaffected by back pressure at port 2 up to its set threshold. It can serve as an alternative to two-port relief valves when there is return line pressure. The RSHCLAN features interchangeable three-port sequence cartridges, ensuring compatibility in terms of flow path and cavity for a specific frame size. As pressure at port 1 increases above the valve setting relative to port 3, pilot flow continues to rise. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the maximum allowable pressure at port 3 should not exceed 5000 psi (350 bar). This model is unsuitable for load holding applications due to spool leakage but incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or cavity/cartridge machining variations. The RSHCLAN has a capacity of 60 gpm (240 L/min) and operates under a maximum pressure of 5000 psi (350 bar). It exhibits control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) with typical response times around 10 ms and maximum valve leakage of approximately 4 in\u00b3/min (65 cc/min) at specified conditions. Adjustments are made via clockwise turns, with five full rotations needed for increased settings. Installation requires specific torque values: valve installation torque between 150-160 lbf ft (203-217 Nm), adjustment screw internal hex size of ^5/32 in., locknut hex size of ^9/16 in., and locknut torque ranging from 80-90 lbf in (9-10 Nm). The model weighs approximately 1.50 lb (0.70 kg), and Viton seal kits are available under part number 990017006.
