The Sun Hydraulics RSHSCQV (RSHSCQV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This model ensures precise pressure control at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can also regulate pressure in place of 2-port relief valves if there's pressure in the return line. The RSHSCQV is interchangeable with other 3-port sequence cartridges, featuring identical flow paths and cavity dimensions for a given frame size. As inlet pressure at port 1 surpasses the valve setting, pilot flow increases correspondingly. The main stage orifice is safeguarded by a 150-micron stainless steel screen, with pressure at port 3 directly adding to the valve setting at a 1:1 ratio, not exceeding 5000 psi (350 bar). This valve is suitable for load-holding applications and resists cavitation-related issues like noise and manifold erosion due to internal modulation within the cartridge. It can handle maximum pressure at port 2, making it ideal for cross-port relief circuits. The Sun floating style construction minimizes risks of internal part binding from excessive installation torque or machining variations. With a capacity of up to 60 gpm (240 L/min) and maximum operating pressure of 5000 psi (350 bar), this model offers fast response times typically around 10 ms and minimal leakage upon reseat. Installation requires specific torque settings for various components such as the valve hex size of 1-1/4 inches (31.8 mm) and locknut torque between 80-90 lbf-in (9-10 Nm). The cartridge uses Viton seals with optional seal kits available for maintenance or replacement needs.

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.
