The Sun Hydraulics RSDCWDV (RSDCWDV) is a pilot-operated, balanced piston sequence valve designed to manage flow to a secondary circuit once the pressure at the inlet port exceeds the valve setting. This valve is adept at controlling pressure at port 1 in relation to the drain port, and it remains unaffected by back pressure at port 2 up to its set limit. It serves as an alternative to 2-port relief valves when there's pressure in the return line. The RSDCWDV model boasts interchangeability among all 3-port sequence cartridges, maintaining consistent flow paths and cavity dimensions for a given frame size. Key features include a main stage orifice shielded by a 150-micron stainless steel screen and an additive pressure capability at port 3 of up to 5000 psi. However, it is not recommended for load-holding applications due to spool leakage. The valve offers adjustable settings via W or Y controls, with options for special settings that define maximum limits. Corrosion-resistant versions are available with stainless steel or zinc-nickel plating, identifiable by specific model code suffixes. The floating style construction minimizes potential binding from installation torque or machining variations. Specifications include a capacity of 15 gpm, maximum operating pressure of 5000 psi, control pilot flow between 7-10 in\u00b3/min., typical response time of 10 ms, and maximum leakage rate of 2 in\u00b3/min at specified conditions. Adjustments can be made through internal hex screws with locknut provisions for secure settings, while installation requires specific torque values for optimal performance.

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.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
- 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.
