Abstract
A pressure reducing valve for gas is provided in which a connecting passage providing a connection between a passage and a pressure action chamber is formed within a valve body, a guide hole guiding movement of the valve body between a spring chamber and a high pressure chamber is formed within a body, a spring linked to a piston and urging the valve body in an opening direction is provided within the spring chamber, and a seal member providing a seal between the high pressure chamber and the spring chamber is disposed between the guide hole and the valve body. This provides a pressure reducing valve for gas that can suppress problems based on a decrease in the temperature of a pressure reducing valve.
