The Sun Hydraulics RSHCYWV (RSHCYWV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This sequence valve controls the pressure at port 1 relative to the pressure at drain port 3 and remains insensitive to back pressure at port 2 up to the valve setting. It can regulate pressure in place of two-port relief valves if there is existing pressure in the return line. The RSHCYWV model features interchangeable three-port sequence cartridges that offer consistent flow paths and cavities for a given frame size. As the pressure at port 1 rises above the valve setting, pilot flow increases accordingly. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and pressure at port 3 directly adds to the valve setting at a 1:1 ratio without exceeding 5000 psi (350 bar). This model is not suitable for load holding applications due to spool leakage. The RSHCYWV incorporates Sun's floating style construction, minimizing internal parts binding from excessive installation torque or cavity/cartridge machining variations. It has a capacity of up to 60 gpm (240 L/min) and operates under a maximum pressure of 5000 psi (350 bar), with control pilot flow ranging from 15-20 in\u00b3/min (0.25-0.33 L/min). Typical response time is around 10 ms, and maximum valve leakage is capped at four in\u00b3/min (65 cc/min) under specified conditions. The adjustment allows for five clockwise turns to increase settings, with specific dimensions provided for hex sizes and installation torques. The product weighs approximately 1.50 lb (0.70 kg) and includes Viton seal kits as part of its design specifications.

Pilot-operated, balanced piston sequence valves will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3). These valves are insensitive to back pressure at port 2 (sequence), up to the valve setting. They may be used to regulate pressure in place of 2-port relief valves if there is pressure in the return line.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Pilot flow continues to increase as the pressure at port 1 (inlet), relative to the pressure at port 3 (drain), rises above the valve setting.
- The main stage orifice is protected by a 150 micron stainless steel screen.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Not suitable for use in load holding applications due to spool leakage.
- W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
