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 RSFCKCN (RSFCKCN) 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 product controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. It can regulate pressure in place of two-port relief valves when there is return line pressure. The RSFCKCN model is interchangeable with other three-port sequence cartridges of the same frame size, ensuring consistent flow paths and cavity compatibility. It features 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. However, it is not recommended for load-holding applications due to spool leakage. This sequence valve incorporates Sun's floating style construction, minimizing internal part binding risks from excessive installation torque or machining variations. It has a capacity of 30 gpm (120 L/min) and factory pressure settings established at 4 gpm (15 L/min). The control pilot flow ranges between 10-15 in\u00b3/min (0.16-0.25 L/min), with a typical response time of 10 ms. Its maximum valve leakage is rated at 3 in\u00b3/min at 110 SUS (24 cSt) under a pressure of 1000 psi (70 bar). The adjustment mechanism allows for five full clockwise turns to increase settings, with specific dimensions and torque requirements provided for installation. The RSFCKCN can be configured with EPDM seals for use with phosphate ester fluids but should avoid petroleum-based fluids due to potential seal damage. Weighing approximately .50 lb (.25 kg), this model includes detailed specifications for adjustment screw sizes and locknut torques, ensuring precise installation and operation within hydraulic systems.

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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
