The Sun Hydraulics RSHSLCN (RSHSLCN) is a pilot-operated, balanced poppet sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. It controls the pressure at port 1 relative to the drain port 3 and is insensitive to back pressure at port 2 up to the valve setting. These valves can regulate pressure in place of two-port relief valves if there is pressure in the return line. The RSHSLCN model features interchangeable three-port sequence cartridges, offering consistent flow paths and cavity compatibility across frame sizes. With a main stage orifice protected by a 150-micron stainless steel screen, this valve ensures durability and reliability. The pressure at port 3 directly adds to the valve setting at a 1:1 ratio, with a maximum limit of 5000 psi (350 bar), making it suitable for load-holding applications. Its design minimizes issues associated with cavitation, such as noise and manifold erosion, due to internal modulation within the cartridge. This model can handle maximum pressure at port 2 and is apt for cross-port relief circuits. It incorporates Sun's floating style construction to reduce internal part binding risks from excessive installation torque or machining variations. The RSHSLCN has a capacity of 60 gpm (240 L/min) with factory pressure settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with a typical response time of 10 ms and minimal leakage upon reseat. This robust unit requires specific installation torques for optimal performance and includes adjustment features for precise control settings.
