The Sun Hydraulics RSFSLCV (RSFSLCV) 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 is engineered to control the pressure at port 1 relative to the pressure at drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can serve as a regulator in place of two-port relief valves when there is pressure in the return line. All three-port sequence cartridges are interchangeable in terms of flow path and cavity for a given frame size. As the pressure at port 1 inlet increases relative to port 3 drain, pilot flow continues to rise above the valve setting. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and pressure at port 3 adds directly to the valve setting at a 1:1 ratio, with an upper limit of 5000 psi (350 bar). This makes it suitable for load-holding applications and cross-port relief circuits. The internal modulating mechanism provides immunity against cavitation-related issues such as noise and manifold erosion. The Sun floating style construction reduces risks of internal parts binding due to excessive installation torque or machining variations. It has a capacity of 30 gpm (120 L/min) with factory settings established at 4 gpm (15 L/min) and maximum operating pressure of 5000 psi (350 bar). The typical response time is about 10 ms, with maximum leakage upon reseat being approximately 10 drops/min (0.7 cc/min). For adjustments, five clockwise turns increase settings, with specific torque requirements for installation and locknut adjustments provided for optimal performance and reliability.

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.
