The Sun Hydraulics RSHSLBN (RSHSLBN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. This sequence valve effectively controls the pressure at port 1 in relation to the drain port 3, remaining unaffected by back pressure at port 2 up to the valve setting. It can substitute for two-port relief valves when there is return line pressure and is suitable for load holding applications. The valve features interchangeable three-port sequence cartridges that maintain consistent flow paths and cavity compatibility within a given frame size. A key characteristic of this model is its internal modulating mechanism, which prevents cavitation-related issues such as noise and erosion. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the valve setting can be directly influenced by the pressure at port 3 in a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). The RSHSLBN utilizes Sun's floating style construction to minimize risks of internal binding due to excessive installation torque or machining variations. It has a capacity of handling up to 60 gpm (240 L/min) and operates optimally with factory settings established at 4 gpm (15 L/min). The typical response time is approximately 10 ms, with maximum valve leakage at reseat being limited to 10 drops/min (0.7 cc/min). Installation specifications include a hex size of 1-1/4 in (31.8 mm), installation torque between 150-160 lbf ft (203-217 Nm), and an adjustment screw internal hex size of 5/32 in (4 mm). The model weighs approximately 1.50 lb (0.70 kg) and includes a Viton seal kit option under 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.
