The Sun Hydraulics RSFCJAV (RSFCJAV) is a pilot-operated, balanced piston sequence valve designed to manage the flow to a secondary circuit once the inlet port 1 pressure surpasses the valve setting. It maintains control over the pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its set threshold. This valve can also be utilized as an alternative to two-port relief valves when there's pressure in the return line. Notably, all three-port sequence cartridges share physical and functional interchangeability for a given frame size, ensuring consistent flow paths and cavity compatibility. The RSFCJAV features a main stage orifice shielded by a 150-micron stainless steel screen and can handle pressures at port 3 up to 5000 psi (350 bar) directly additive to its setting. However, it is not suitable for load-holding applications due to potential spool leakage. The valve offers W and Y controls with adjustable settings across their full range unless specified with a special maximum setting. Cartridges configured with EPDM seals are compatible with phosphate ester fluids but vulnerable to petroleum-based substances. The construction incorporates Sun's floating style design, which reduces internal binding risks from excessive installation torque or machining variations. With a capacity of 30 gpm (120 L/min), it operates at a maximum pressure of 5000 psi (350 bar) and typical response time of 10 ms. The valve's leakage rate is minimal at standard conditions, making it efficient for various hydraulic applications requiring precise pressure management without compromising system integrity.

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.
