The utility model relates to the technical field of valves, in particular to a two-way and three-way manual pneumatic chemical plunger valve which comprises a valve body, a valve element is installedin the valve body, a liquid inlet and a liquid outlet are formed in the valve body, and the upper portion of the valve element penetrates out of the valve body and is connected with a steering device.Compared with the prior art, the two-way and three-way manual pneumatic chemical plunger valve is reasonable in structure and easy to manufacture, the valve element can be driven to move relative tothe valve body in a manual or pneumatic mode according to needs, the sealing performance during rotation is kept through the sealing ring, and the service life of the valve element is prolonged. 50,000 times of switch voltage maintaining tests (which can be used under 10bar pressure) can be easily achieved; a multi-fluid channel is adopted between the liquid inlet and the liquid outlet, so that the through-flow area of a fl
