The Sun Hydraulics RSHCKDV (RSHCKDV) 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 valve controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to its setting, making it suitable for regulating pressure in place of two-port relief valves when there is return line pressure. The RSHCKDV features interchangeable three-port sequence cartridges, maintaining consistent flow paths and cavity sizes across frame sizes. It incorporates a main stage orifice protected by a 150-micron stainless steel screen and supports a maximum operating pressure of 5000 psi (350 bar). However, it is not suitable for load-holding applications due to spool leakage. The valve's design includes Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It allows for adjustable settings using W or Y controls, with options for special settings representing maximum valve settings. The model has a capacity of 60 gpm (240 L/min) and exhibits typical response times of around 10 ms. With an installation torque range of 150-160 lbf ft (203-217 Nm) and adjustment screw internal hex size of 5/32 in (4 mm), it offers reliable performance in hydraulic systems. The RSHCKDV also comes with a Viton seal kit option for enhanced durability, weighing approximately 1.50 lb (0.70 kg).

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.
