The Sun Hydraulics RSJSLAV (RSJSLAV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port exceeds the valve setting. This valve features insensitivity to back pressure at the sequence port, making it suitable for use in cross-port relief circuits. It can regulate pressure in place of two-port relief valves if there's pressure in the return line. The RSJSLAV is interchangeable with other three-port sequence cartridges, maintaining identical flow paths and cavity sizes for a given frame size. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the valve can handle pressures up to 5000 psi (350 bar). It incorporates Sun's floating style construction to minimize binding issues due to installation torque or machining variations. The RSJSLAV allows pilot flow to increase as inlet pressure rises above the setpoint relative to drain pressure, with port 3's pressure directly adding to the setpoint at a 1:1 ratio. Its maximum operating capacity is 120 gpm (480 L/min), with typical response times around 2 ms and leakage at reseat limited to 10 drops/minute. The adjustment mechanism allows up to five clockwise turns for setting increases, with specific torque requirements for installation and locknut adjustments. Weighing approximately 3.10 lb (1.40 kg), this valve is equipped with Viton seals and offers robust performance in hydraulic systems where precise sequencing control is essential.

Pilot-operated, balanced poppet 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).
- Because the modulating occurs inside the cartridge these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- 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.
