The Sun Hydraulics RSHCLCN (RSHCLCN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. This sequence valve manages the pressure at port 1 relative to the drain port 3 and is unaffected by back pressure at port 2 up to the valve setting. It can substitute for 2-port relief valves when there is return line pressure. The RSHCLCN model features interchangeable cartridges for all 3-port sequence types, meaning they have identical flow paths and cavities for a given frame size. As the inlet pressure at port 1 rises above the valve setting relative to port 3, pilot flow increases continuously. The main stage orifice is safeguarded by a robust 150-micron stainless steel screen. The pressure at port 3 adds directly to the valve setting in a 1:1 ratio, with a maximum limit of 5000 psi (350 bar). This model is not suitable for load-holding applications due to spool leakage. The design includes Sun's floating style construction, which reduces binding risks from excessive installation torque or machining variations in cavity/cartridge interfaces. It has a T-17A cavity and Series-3 capacity of up to 60 gpm (240 L/min). Factory settings are established at a flow rate of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), and typical response time is around 10 ms. Maximum leakage under specified conditions is limited to approximately four in\u00b3/min (65 cc/min). The adjustment mechanism allows up to five clockwise turns for increasing settings, with specific dimensions provided for installation and adjustment tools. The model weighs approximately 1.50 lb (0.70 kg) and includes Viton seal kits 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.
- 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.
