The Sun Hydraulics RSFSKQV (RSFSKQV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This sequence valve controls 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. The RSFSKQV can regulate pressure in place of two-port relief valves when there is return line pressure and is suitable for load holding applications. With its interchangeable design, all three-port sequence cartridges maintain the same flow path and cavity for a given frame size. The valve features a main stage orifice protected by a 150-micron stainless steel screen and can handle pressures up to 5000 psi (350 bar). Its design incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. The RSFSKQV accepts maximum pressure at port 2, making it ideal for cross-port relief circuits. It boasts a response time of approximately 10 ms and maintains maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The adjustment mechanism allows up to five clockwise turns to increase settings, with specific dimensions provided for installation torque and adjustment components. This model weighs approximately .50 lb (.25 kg) and comes with an optional Viton seal kit (990402006).

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).
- Suitable for use in load holding applications.
- 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.
