Product Operation Symbol
The Hydraulic control check valve 30AY-10 allows flow from ②to ③, while normally blocking oil flow in the opposite direction. The flow will be allowed from ③ to ② when sufficient pressure is applied at ①. The cartridge has a 2:1 pilot ratio, meaning that at least one-half 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.Performance/Dimension
