とを特徴とする残圧排気弁。[Claim for Utility Model Registration] Pressurization in a flow path connecting a directional switching valve installed on a manifold with a flow path that functions as piping and a pneumatic actuator controlled by the directional switching valve. In a residual pressure exhaust valve for exhausting air, the valve body includes a through hole for connecting the flow path of the manifold and the directional switching valve, and a through hole that connects the directional switching valve and the pneumatic actuator. forming an air chamber that communicates with the first and second through holes forming a connecting flow path and communicating with the atmosphere;
A first check valve that allows air flow from the through hole to the air chamber and blocks air flow in the opposite direction is disposed, and a second check valve is provided in the passage communicating the second through hole and the air chamber.
A second check valve is provided which allows air to flow from the vent to the air chamber and prevents air from flowing in the opposite direction, and which normally closes the passage connecting the air chamber to the atmosphere. What is claimed is: 1. A residual pressure exhaust valve characterized in that an on-off valve that can open the passage by manual operation from the outside is provided.
