Pilot operated, balanced piston relief valve Capacity: 12 gpm (45 L/min.) Functional Group: Products : Cartridges : Relief : 2 Port : Pilot Operated, Balanced Piston Model: RPCC-LAN Product Description Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast. Technical Features All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size). Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio. Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage. The main stage orifice is protected against contamination. Minimum setting is 75 psi (5 bar) for all spring ranges. 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. Not suitable for use in load holding applications due to spool leakage.
