The Sun Hydraulics RSHCCWV (RSHCCWV) is a pilot-operated, balanced piston sequence valve designed to manage flow in secondary circuits once the inlet pressure at port 1 surpasses the set threshold. This model regulates pressure at port 1 concerning the drain port 3 and remains unaffected by back pressure at port 2 up to the valve's setting. The RSHCCWV can substitute for two-port relief valves when there is return line pressure and features physical and functional interchangeability across all three-port sequence cartridges of the same frame size. As inlet pressure at port 1 rises above the setting, pilot flow increases, with a main stage orifice protected by a 150-micron stainless steel screen. The valve setting is directly influenced by pressure at port 3, which should not exceed 5000 psi (350 bar). It's important to note that this valve is unsuitable for load-holding applications due to spool leakage. The RSHCCWV includes W and Y controls for adjusting settings throughout its full range unless a special maximum setting is specified. It utilizes Sun's floating style construction to prevent internal part binding from excessive installation torque or cavity/cartridge 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), and control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min). The typical response time is around 10 ms, with maximum valve leakage at specified conditions being approximately 4 in\u00b3/min (65 cc/min). Adjustment involves up to five clockwise turns, with installation torque ranging from 150-160 lbf\u00b7ft (203-217 Nm). The model weighs approximately 1.50 lb (0.70 kg) and uses Viton seal kits for durability in various applications.
