The Sun Hydraulics RSDCCWV (RSDCCWV) is a pilot-operated, balanced piston sequence valve designed to manage hydraulic flow in secondary circuits once the inlet pressure at port 1 surpasses the pre-set threshold. This valve efficiently controls the pressure at port 1 relative to port 3, making it insensitive to back pressure at port 2 up to its setting. It can substitute for two-port relief valves when there is return line pressure and is not suitable for load-holding applications due to spool leakage. The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability. Pressure at port 3 adds directly to the valve setting in a 1:1 ratio, with a maximum limit of 5000 psi (350 bar). The RSDCCWV model features corrosion-resistant options with external stainless steel or zinc-nickel plated components identified by suffixes AP or LH, respectively. It integrates Sun's floating style construction to reduce risks of internal binding from installation torque or machining variations. This sequence valve fits into cavity T-11A, Series 1, offering a capacity of 15 gpm (60 L/min) and operates optimally under factory settings established at 4 gpm (15 L/min). With a control pilot flow ranging from 7-10 in\u00b3/min (0.11-0.16 L/min) and typical response time of approximately 10 ms, it ensures precise performance under demanding conditions. Additional specifications include an adjustment range facilitated by W or Y controls without special settings unless specified otherwise, and installation requirements such as a valve hex size of 7/8 inch (22.2 mm) and torque specifications between 30-35 lbf ft (41-47 Nm).

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.
