Product Operation Symbol
The Hydraulic control check Valve 30AY-S30 allows flow from ② to ①, while normally blocking oil flow in the opposite direction. The flow will be allowed from ① to ②when sufficient pressure is applied at ③.The check is spring-biased to assure holding in static or no-load conditions.
