The Sun Hydraulics RSFCMNV (RSFCMNV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port 1 exceeds the valve setting. This valve controls the pressure at port 1 relative to the pressure at drain port 3, while being insensitive to back pressure at port 2 up to the valve setting. It can regulate pressure in place of 2-port relief valves if there is pressure in the return line. All three-port sequence cartridges are interchangeable in terms of flow path and cavity for a given frame size. As the inlet pressure at port 1 increases relative to drain port 3, pilot flow continues to rise above the valve setting. The main stage orifice features a protective 150-micron stainless steel screen. The maximum allowable pressure at port 3 is additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). This product is not suitable for load holding applications due to spool leakage. The RSFCMNV includes W and Y controls that can be specified with or without a special setting, adjustable throughout its full range unless otherwise specified. Cartridges with EPDM seals are intended for use with phosphate ester fluids and should avoid exposure to petroleum-based fluids. The floating style construction minimizes internal part binding due to excessive installation torque or machining variations. This Series 2 cartridge has a capacity of 30 gpm (120 L/min) and operates up to a maximum pressure of 5000 psi (350 bar). Factory settings are established at a flow rate of 4 gpm (15 L/min), with control pilot flow ranging from 10-15 in\u00b3/min (0.16-0.25 L/min). The typical response time is approximately 10 ms, and maximum leakage is limited to three in\u00b3/min at an operating viscosity of SUS24 cSt under conditions of up to 1000 psi (70 bar).
