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 RSJCKDN (RSJCKDN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. It effectively controls the pressure at port 1 relative to the drain port 3 and remains insensitive to back pressure at port 2 up to the valve setting. This makes it suitable for regulating pressure in place of 2-port relief valves when there is return line pressure. The RSJCKDN features interchangeable 3-port sequence cartridges, maintaining consistent flow paths and cavity sizes across frames. The valve includes a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures up to 5000 psi (350 bar) at port 3, which adds directly to the valve setting at a 1:1 ratio. However, it is not recommended for load-holding applications due to spool leakage. For control options, W and Y adjustments allow for full-range settings unless specified otherwise with a special maximum setting. The RSJCKDN incorporates Sun's floating style construction, minimizing internal binding risks due to excessive installation torque or machining variations. It fits Cavity T-19A Series 4 and has a capacity of up to 120 gpm (480 L/min). Factory pressure settings are established at flows of 4 gpm (15 L/min), with a maximum operating pressure of 5000 psi (350 bar). Control pilot flow ranges from 15-20 in\u00b3/min (0.25-0.33 L/min), and typical response time is around 10 ms. The valve's maximum leakage rate is specified as five in\u00b3/min at 110 SUS (24 cSt) under conditions of up to 1000 psi (70 bar). Installation requires specific torques for various components, such as an adjustment screw internal hex size of ^5/32 inch and locknut torque between 80-90 lbf-in (9-10 Nm). The model weighs approximately 3.10 lb (1.40 kg) and uses Viton seal kits for optimal performance.

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.
