Claims

[Claims for Utility Model Registration] A casing having an inlet and an outlet, a pair of valve seats and a valve body that open and close a flow path between the inlet and the outlet, a valve shaft that supports the valve body, A diaphragm connected to the valve stem and configured to move the valve body in a direction in which it comes into contact with the valve seat in response to fluid pressure flowing out; and a coil spring that urges the diaphragm in a direction in which the valve body separates from the valve seat. and,
In the pressure reducing valve equipped with a spring holder that adjusts the biasing force of the coil spring, the inflow port and the outflow port are provided opposite to each other with the diaphragm interposed therebetween, and the diaphragm is connected with the valve shaft passing through the diaphragm. A through hole is provided along the longitudinal axis of the valve shaft to form a flow path from the inflow port to the outflow port via between the valve seat and the valve body, and the diaphragm is connected to the flow path. 1. A pressure reducing valve, wherein the coil spring is disposed perpendicularly to the flow path, and the coil spring is disposed so as to surround the flow path, and the direction of action of the coil spring is along the flow path.
