The Sun Hydraulics RSDCKDV (RSDCKDV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. It 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. These valves can replace 2-port relief valves when there's pressure in the return line. The interchangeable nature of all three-port sequence cartridges allows for consistent flow paths and cavity compatibility across frame sizes. The valve features a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures at port 3 up to 5000 psi (350 bar). However, it is not suitable for load holding applications due to spool leakage. The RSDCKDV offers adjustable controls with options for special settings that define maximum valve settings. Corrosion-resistant versions are available, identifiable by model code suffixes like AP or LH, indicating external stainless steel or zinc-nickel plated components, respectively. This cartridge incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. With a cavity T-11A Series 1 capacity of 15 gpm (60 L/min) and factory pressure settings established at 4 gpm (15 L/min), this valve operates under a maximum pressure of 5000 psi (350 bar). It features a control pilot flow of 7 - 10 in\u00b3/min (0.11 - 0.16 L/min) and typical response time of around 10 ms. Maximum valve leakage is rated at 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation specifications include an adjustment screw internal hex size of 5/32 in., locknut hex size of 9/16 in., and torque requirements for both adjustments and installation range from specific foot-pound values. The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits identified by 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.
