The Sun Hydraulics RSHSLAV (RSHSLAV) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This valve effectively manages 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 replace 2-port relief valves when there is pressure in the return line. The RSHSLAV model features a design where all three-port sequence cartridges are interchangeable in both physical and functional aspects, ensuring compatibility within a given frame size. An increase in pilot flow corresponds with rising inlet pressure at port 1 relative to drain pressure at port 3 beyond the valve setting. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and pressures up to 5000 psi (350 bar) are additive to the valve setting on a one-to-one basis. This model is particularly suitable for load-holding applications and can handle maximum pressures at port 2, making it ideal for cross-port relief circuits. Its construction minimizes internal binding issues due to excessive installation torque or machining variations, thanks to Sun's floating style design. With a cavity size of T-17A and series compatibility of 3, this cartridge has a flow capacity of up to 60 gpm (240 L/min) and operates under maximum pressures of up to 5000 psi (350 bar). It features rapid response times typically around 10 ms and minimal leakage upon reseating. Installation specifications include a hex size of 1-1/4 inches with an installation torque between 150-160 lbf ft (203-217 Nm). The adjustment screw requires an internal hex size of 5/32 inches for tuning, accompanied by a locknut hex size of 9/16 inches tightened between 80-90 lbf in (9-10 Nm). The model weighs approximately 1.50 lb (0.70 kg), and it includes Viton seal kits for optimal performance in hydraulic systems.

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.
