***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. 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 RSDCLAN (RSDCLAN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This valve controls the pressure at port 1 relative to the pressure at the drain port 3 and remains unaffected by back pressure at port 2 up to its setting. It can replace 2-port relief valves in scenarios with return line pressure. All three-port sequence cartridges are interchangeable in terms of flow path and cavity size for a given frame size. The valve features a stainless steel screen protecting the main stage orifice and can handle pressures at port 3 that are additive to the valve setting but should not exceed 5000 psi (350 bar). However, it is not recommended for load-holding applications due to spool leakage. The valve offers W and Y control options, adjustable throughout their range unless a special setting is specified, representing the maximum setting. Corrosion-resistant versions are available, identifiable by model code suffixes AP or LH for external stainless steel or zinc-nickel plated components, respectively. The Sun floating style construction minimizes binding risks from excessive torque or machining variations. Key specifications include a T-11A cavity, Series 1 capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), and control pilot flow between 7-10 in\u00b3/min (0.11-0.16 L/min). The typical response time is around 10 ms, with maximum leakage at approximately 2 in\u00b3/min under specific conditions. Installation requires certain torques for adjustment screw and locknut, with adjustment via an internal hex size of 5/32 inches and locknut hex size of 9/16 inches. The model weighs .30 lb (.15 kg), with Viton seal kit part number: 990011006 available for maintenance needs.

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.
