The Sun Hydraulics RSHSCAN (RSHSCAN) 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 valve precisely controls the pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to its preset value. It can be utilized as a substitute for two-port relief valves when there is return line pressure. The RSHSCAN model is part of Sun's interchangeable three-port sequence cartridges, sharing the same flow path and cavity for a given frame size. It features a main stage orifice shielded by a 150-micron stainless steel screen and can handle pressures up to 5000 psi (350 bar) at port 3, which adds directly to the valve setting on a 1:1 basis. This sequence valve is adept for load-holding applications and mitigates common cavitation issues such as noise and manifold erosion due to its internal modulating mechanism. It accepts maximum pressure at port 2, making it suitable for cross-port relief circuits. The Sun floating style construction minimizes internal part binding risks from excessive installation torque or machining variations. The RSHSCAN has a capacity of 60 gpm (240 L/min) with factory settings established at 4 gpm (15 L/min). It boasts a typical response time of 10 ms and limits maximum valve leakage at reseat to 10 drops/min (0.7 cc/min). The adjustment requires five clockwise turns to increase settings, with specific torque requirements for installation and adjustment components provided for optimal performance. The model weighs approximately 1.50 lb (0.70 kg) and uses Viton seals available in cartridge form as part number 990217006.

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.
