The valve includes a valve body made of a metal material and a valve plug, and the valve plug selectively seals the valve body. The utility of controlling the flow state of the high pressure gas is achieved. When the gas valve is in a flow state, the valve plug is partially fulcrum and abuts against the valve body to perform a yaw-like yaw action, and the pressing force between the two is concentrated at the contact portion thereof, because the valve plug is made of plastic material. It is easy to cause the contact part corresponding to the valve plug to be pressed. After long-term use, there will be a problem of collapse, which will result in an uneven structure on the surface of the valve plug, which will result in the valve plug and the valve body not being tightly sealed and lowered.

The top surface of the protrusion 23 is biased like a seesaw, so that the top surface 222 of the base 221 is relatively far from the first ring protrusion 212 of the seal ring 21 and does not interfere with each other, thereby avoiding the valve plug surface of the conventional valve. The problem of collapse. Thereby, the airtight state of the base 221 and the seal ring 21 is broken, and the high pressure gas is caused to flow between the base 221 and the seal ring 21, and is introduced into the cylinder rotor module 11 from the intake passage 14, and drives the rotary shaft 13 , causing the pneumatic tool A to perform routine work.
