The Sun Hydraulics RSJCLBN (RSJCLBN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. It controls the pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. These valves can substitute for two-port relief valves if there is pressure in the return line and are interchangeable with all three-port sequence cartridges of the same frame size. The valve features a main stage orifice protected by a 150-micron stainless steel screen and a maximum operating pressure of 5000 psi (350 bar). It is not suitable for load holding applications due to spool leakage. The RSJCLBN incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. With a capacity of 120 gpm (480 L/min), the factory pressure settings are established at 4 gpm (15 L/min). The control pilot flow ranges from 15 to 20 in\u00b3/min (0.25 to 0.33 L/min), with typical response times around 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is measured at 5 in\u00b3/min (80 cc/min) under conditions of up to 1000 psi (70 bar). Adjustment of this valve involves up to five clockwise turns, with specific hex sizes and torque specifications for various components, such as a valve hex size of 1-5/8 in. (41.3 mm) and installation torque between 350-375 lbf ft (474-508 Nm). The model weighs approximately 3.10 lb (1.40 kg) and includes a Viton seal kit option coded as cartridge: Viton: 990019006, ensuring reliable performance across diverse hydraulic applications where sequencing functions are critical.

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.
