The Sun Hydraulics RSHSKQV (RSHSKQV) 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. Its design ensures that the pressure at port 1 is regulated relative to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. This makes it suitable for use in load holding applications and cross-port relief circuits. The valve features interchangeable 3-port sequence cartridges with consistent flow paths and cavity sizes for a given frame size. A stainless steel screen protects the main stage orifice, and its response time is typically around 10 ms. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 60 gpm (240 L/min), this valve is built for high-performance applications. It incorporates Sun's floating style construction to prevent internal binding due to installation torque or machining variations. The RSHSKQV model supports adjustments with five clockwise turns needed to increase settings, and it includes specific torque requirements for installation and locknut adjustments. Additionally, it offers minimal valve leakage at reseat, ensuring reliability in demanding conditions.

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.
