Pilot operated, balanced piston sequence valve Capacity: 15 gpm (60 L/min.) Functional Group: Products : Cartridges : Sequence : 3-Port : Pilot Operated, Balanced Piston Model: RSDC-LAN Product Description Pilot-operated, balanced piston 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. Technical Features All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). Not suitable for use in load holding applications due to spool leakage. 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. Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP (see Option Selection below). External parts are made from stainless steel with titanium or brass components, where applicable. Internal parts are made from carbon steel leaded alloy, the same as standard valves. For further details, please see the Materials of Construction page. The main stage orifice is protected by a 150 micron stainless steel screen. 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. Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
