The Sun Hydraulics RSDCWEV (RSDCWEV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This specific model is part of Sun Hydraulics' range of 3-port sequence cartridges, which are both physically and functionally interchangeable, ensuring compatibility across similar frame sizes. The RSDCWEV valve is adept at controlling pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve's set threshold. It can also regulate pressure in lieu of 2-port relief valves when return line pressure is present. Key features include a stainless steel screen protecting the main stage orifice and a maximum operating pressure capacity of 5000 psi (350 bar). The valve\u2019s pilot flow increases with rising inlet pressures above its setting, while response time typically clocks in at around 10 milliseconds. The RSDCWEV model is not recommended for load-holding applications due to potential spool leakage. For environments subject to corrosion, this cartridge valve can be specified with external stainless steel (AP suffix) or zinc-nickel plating (LH suffix). The design incorporates Sun's floating style construction, which reduces internal part binding risks due to installation torque or machining variations. Adjustment options are available through W and Y controls for full-range adaptability or specific settings as needed. The installation requires specific torques and hex sizes for both the valve and locknut components. This model's seal kit uses Viton material, ensuring durability under various conditions. Overall, the RSDCWEV offers reliable performance in applications requiring precise control over hydraulic sequencing functions.

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.
