Operation Symbol of IPC12-30 Check Valve, Pilot-to-Open (Dual-Pilot-Operated)

The IPC12-30 allows flow from② to①, while normally blocking oil flow in the opposite direction. A small amount of flow will pass from① to② when sufficient pressure is applied at③, to reduce the load pressure at port①, and the required pilot pressure to unlock the main stage will decrease with the reduction of load pressure, which allows the flow from①to② completely with sufficient pilot pressure.
The cartridge has a 25:1 pressure reducing ratio and a 3:1 pilot ratio. The check is spring-biased to assure holding in static or no-load conditions.
Note: The pilot pressure will 1:1 increase upon the back pressure on port② during calculating.
