The Sun Hydraulics RSFCLEN (Material Number: RSFCLEN) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This valve effectively controls the pressure at port 1 in relation to the drain port 3, remaining insensitive to back pressure at port 2 up to its set limit. It can function as a pressure regulator, replacing two-port relief valves when there is return line pressure. Its design allows for physical and functional interchangeability among all three-port sequence cartridges of the same frame size, ensuring compatibility with existing systems. The RSFCLEN features a main stage orifice protected by a 150-micron stainless steel screen and supports maximum operating pressures of up to 5000 psi (350 bar). The valve's pressure setting is directly impacted by port 3's pressure at a 1:1 ratio, which should not exceed its maximum limit. However, it is not suitable for load-holding applications due to potential spool leakage. The valve's adjustment capabilities include W and Y controls, allowing for full range adjustability unless specified otherwise. This sequence valve incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations. It supports a flow capacity of up to 30 gpm (120 L/min) and has a typical response time of around 10 milliseconds. The RSFCLEN uses EPDM seals compatible with phosphate ester fluids but should avoid petroleum-based products to prevent seal damage. Installation specifications include a hex size of 1-1/8 inches (28.6 mm), an installation torque range of 45-50 lbf ft (61-68 Nm), and an adjustment screw internal hex size of 5/32 inches (4 mm).

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.
