The Sun Hydraulics RSDCLCV (RSDCLCV) is a sophisticated pilot-operated, balanced piston sequence valve designed to manage secondary circuit flow once the pressure at inlet port 1 surpasses the valve's set threshold. This valve effectively regulates pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can substitute for two-port relief valves where return line pressure exists. The three-port sequence cartridges are interchangeable, maintaining consistent flow paths and cavity requirements across frame sizes. As inlet pressure at port 1 increases relative to drain port 3, pilot flow correspondingly rises beyond the valve setting. The main stage orifice benefits from a protective 150-micron stainless steel screen, ensuring durability and performance integrity. This model is not recommended for load-holding applications due to potential spool leakage. It offers adjustable W and Y controls, with or without special settings that define maximum valve settings. The RSDCLCV is suitable for corrosive environments when configured with external stainless steel components (suffix AP) or zinc-nickel plating (suffix LH). Its design incorporates Sun\u2019s floating style construction to prevent internal binding caused by excessive installation torque or machining discrepancies. Key specifications include a T-11A cavity, Series 1 capacity of 15 gpm (60 L/min), and a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 7 to 10 in\u00b3/min (0.11 - 0.16 L/min), with a typical response time of 10 ms and maximum leakage of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Adjustment requires up to five clockwise turns to increase settings, with specific torque values outlined for installation and locknut adjustments. The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits identified as 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.
