The Sun Hydraulics RSDCKNV (Material Number: RSDCKNV) is a pilot-operated, balanced piston sequence valve designed to provide flow to a secondary circuit once the inlet pressure at port 1 exceeds the valve setting. This valve is designed to be insensitive to back pressure at port 2 up to the valve setting, making it suitable for regulating pressure in applications where there is return line pressure. It can replace 2-port relief valves under these conditions. The RSDCKNV is part of a range of interchangeable 3-port sequence cartridges, featuring identical flow paths and cavities for given frame sizes. It incorporates a main stage orifice protected by a 150-micron stainless steel screen and allows for pilot flow increase as inlet pressure rises above the setting relative to the drain port. The valve\u2019s maximum operating pressure is 5000 psi (350 bar), with control pilot flow ranging from 7 to 10 in\u00b3/min (0.11 to 0.16 L/min). It features an adjustment mechanism allowing for changes in settings through clockwise turns, with a maximum of five turns available. The valve\u2019s response time is typically around 10 milliseconds, with maximum leakage at specified conditions being minimal. Additionally, the RSDCKNV employs Sun\u2019s floating style construction, minimizing binding risks due to installation torque or machining variations. It comes with corrosion-resistant options identified by model code suffixes AP or LH for external stainless steel or zinc-nickel plating components respectively. The cartridge capacity stands at 15 gpm (60 L/min) with factory pressure settings established at a flow rate of 4 gpm (15 L/min). This product also includes an internal hex size adjustment screw and locknut torque specifications for secure installation and operation.

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.
