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 RSDCLNN (RSDCLNN) is a pilot-operated, balanced piston sequence valve designed to manage secondary circuit flow once the pressure at inlet port 1 surpasses the valve setting. This valve effectively regulates pressure at port 1 relative to the pressure at drain port 3, remaining unaffected by back pressure at port 2 until reaching the valve setting. It serves as an alternative to two-port relief valves in scenarios where there is pressure in the return line. The RSDCLNN model features interchangeable three-port sequence cartridges, ensuring compatibility in flow path and cavity for a given frame size. The pilot flow of this valve increases as the inlet pressure at port 1 rises above the valve setting relative to drain port 3. The main stage orifice is safeguarded by a robust 150-micron stainless steel screen, and it is crucial that pressure at port 3 does not exceed 5000 psi (350 bar), as it directly influences the valve setting on a 1:1 ratio. This model is unsuitable for load holding applications due to spool leakage but offers adjustable settings throughout its range using W or Y controls unless a special maximum setting is specified. Designed for use in corrosive environments, corrosion-resistant options include external stainless steel components (suffix AP) or zinc-nickel plating (suffix LH). The Sun floating style construction minimizes internal part binding due to excessive torque or machining variations. Key specifications include a T-11A cavity series with a capacity of up to 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 approximately 10 ms with maximum valve leakage of about 2 in\u00b3/min at specific conditions.

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.
