The Sun Hydraulics RSBCKWV (RSBCKWV) 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 valve controls the pressure at port 1 relative to the pressure at drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. It can be used as a substitute for 2-port relief valves when there is pressure in the return line. All three-port sequence cartridges are interchangeable, having the same flow path and cavity for a given frame size. The pilot flow increases as the inlet pressure at port 1 rises above the valve setting relative to drain port 3. A stainless steel screen protects its main stage orifice, ensuring durability and reliability. The minimum setting for this model is 75 psi (5 bar), with maximum operating pressure reaching up to 5000 psi (350 bar). It is not suitable for load-holding applications due to spool leakage, and cartridges with EPDM seals are intended for systems using phosphate ester fluids, as petroleum-based substances can damage these seals. Featuring Sun's floating style construction, it minimizes internal part binding risks from excessive installation torque or machining variations. The RSBCKWV has a capacity of 7.5 gpm (30 L/min) with factory pressure settings established at 4 gpm (15 L/min). Its response time is typically around 10 ms, with maximum valve leakage of about 2 in\u00b3/min (30 cc/min) at standard viscosity conditions. The adjustment mechanism allows up to five clockwise turns to increase settings, ensuring precise control over hydraulic operations. This model's compact design includes a hex size of \u00be inch (19.1 mm) for installation torque between 20-25 lbf\u00b7ft (27-33 Nm), making it versatile and efficient for various hydraulic applications.

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.
- Minimum setting is 75 psi (5 bar) for all spring ranges.
- 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.
- 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.
