The Sun Hydraulics RSHCLCV (RSHCLCV) is a pilot-operated, balanced piston sequence valve designed to manage flow in secondary circuits once the pressure at the inlet port exceeds the valve's setting. This valve effectively controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to its set value. It can be utilized as a substitute for two-port relief valves when there is return line pressure. The RSHCLCV model features interchangeable three-port sequence cartridges that maintain consistent flow paths and cavity sizes. It includes a main stage orifice protected by a 150-micron stainless steel screen, and it can handle pressures up to 5000 psi (350 bar). Note that this valve is not suitable for load-holding applications due to spool leakage. The valve allows adjustable settings using W or Y controls, with options for special settings that represent maximum values. Sun's floating style construction helps prevent internal binding from excessive installation torque or machining variations. The RSHCLCV model has a capacity of 60 gpm (240 L/min) and operates with a factory pressure setting established at 4 gpm (15 L/min). Its control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with a typical response time of approximately 10 ms. Maximum leakage is rated at 4 in\u00b3/min (65 cc/min) under specific conditions, and adjustments are made via an internal hex screw with specified torque requirements for locknut adjustments. The model weighs approximately 1.50 lb (0.70 kg) and includes Viton seal kits for enhanced durability and performance in hydraulic systems.
