The Sun Hydraulics RSFCJPV (RSFCJPV) 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 controls the pressure at port 1 relative to the drain port 3, remaining insensitive to back pressure at port 2 sequence up to its set point. It can regulate pressure in place of two-port relief valves where there is pressure in the return line. The valve features interchangeable three-port sequence cartridges, offering identical flow paths and cavities for a given frame size. As the inlet pressure at port 1 rises above the valve setting, pilot flow increases accordingly. The main stage orifice is protected by a robust 150-micron stainless steel screen, and pressure at port 3 adds directly to the valve setting at a one-to-one ratio, withstanding up to 5000 psi (350 bar). However, it is not suitable for load-holding applications due to potential spool leakage. The RSFCJPV allows W and Y control adjustments throughout its range unless a special setting specifies otherwise. Cartridges with EPDM seals are intended for systems using phosphate ester fluids but should avoid petroleum-based substances that could damage seals. The Sun floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations. Specifications include a cavity T-2A series with a capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. Valve leakage remains minimal at specified conditions, and adjustments are made via an internal hex screw with specific torque requirements for installation and locknut settings. The model weighs approximately .50 lb (.25 kg) and includes an available Viton seal kit (990202006).

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.
