SUN Overflow Valve RPGC-LCN For Load Holding Applications Pilot-Operated Balanced-Piston Design

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. All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).

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. Main stage orifice is protected by a 150-micron stainless steel screen.
