The IPC08-30 allows flow from ②to ③, while normally blocking flow from ③ to②. The flflow will be allowed from ③ to ② when sufficient pressure is applied at ①. The cartridge has a 3:1 pilot ratio, meaning that at least one-third of the load pressure held at ③ is required at ① to open the valve. The check is spring-biased to assure holding in static or no-load conditions. A sealed pilot piston option is available.
