The Sun Hydraulics RSBCLNV (RSBCLNV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This sequence valve is engineered to control the pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve's set point. It offers versatility by acting as a pressure regulator in place of two-port relief valves when there is return line pressure. All three-port sequence cartridges are interchangeable in terms of flow path and cavity size for a given frame size. The valve's pilot flow increases as the inlet pressure at port 1 rises above the setting relative to port 3. The RSBCLNV features a main stage orifice protected by a 150-micron stainless steel screen and has a minimum setting of 75 psi (5 bar) for all spring ranges. Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio, with an upper limit of 5000 psi (350 bar). It is not suitable for load-holding applications due to spool leakage. Cartridges configured with EPDM seals are intended for systems using phosphate ester fluids and should avoid contact with petroleum-based substances. This model utilizes Sun's floating style construction, which minimizes internal part binding risks due to excessive torque or machining variations. It has a capacity of 7.5 gpm (30 L/min) and operates up to a maximum pressure of 5000 psi (350 bar). The typical response time is around 10 ms, with maximum leakage rated at approximately 2 in\u00b3/min (30 cc/min) under specified conditions. The cartridge requires specific installation torques and adjustments detailed in its specifications, including an adjustment screw internal hex size of 5/32 inches and locknut torque specifications between 80-90 lbf\u00b7in (9-10 Nm).

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.
