Claims

[Scope of Claim for Utility Model Registration] A valve that is attached to an air pipe for supplying compressed air in order to connect the air pipe for supplying compressed air to a device driven by compressed air, the valve being disposed in an internal passage of a valve body, a valve switching valve having a valve passage capable of communicating with the internal passage and a pressure relief hole branched from the valve passage, and rotatable by a switching device attached to the valve body; A residual pressure relief valve comprising a small hole formed in the side wall of the valve body at a position that coincides with the pressure relief hole and allows communication between the pressure relief hole and the outside when the air supply is stopped. .
