While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics RSDCWCV (RSDCWCV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This valve regulates pressure at port 1 relative to the drain port 3, and is insensitive to back pressure at port 2 up to the valve setting. It can be used in place of 2-port relief valves when there's pressure in the return line. All 3-port sequence cartridges are interchangeable for a given frame size, ensuring compatibility across various applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and pressure at port 3 adds directly to the valve setting at a 1:1 ratio, with a maximum limit of 5000 psi (350 bar). However, it is not suitable for load-holding applications due to spool leakage. The RSDCWCV features corrosion-resistant options identified by model code suffixes AP or LH for external stainless steel or zinc-nickel plated components, respectively. It employs Sun's floating style construction to reduce potential binding from excessive installation torque or machining variations. The cavity T-11A Series 1 has a capacity of up to 15 gpm (60 L/min), with factory settings established at 4 gpm (15 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min) and typical response time around 10 ms. The adjustable settings are achieved via W or Y controls, with or without special settings specified. Adjustment involves up to five turns clockwise for increased settings, using an internal hex size of 5/32 inches and locknut torque between 80-90 lbf-in (9-10 Nm). The cartridge weighs approximately .30 lb (.15 kg) and includes a Viton seal kit option under part number 990011006.

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.
