The pneumatic valve is a special type of valve that is commonly used in chemical, pharmaceutical, and other applications where the flow of gases or liquids needs to be controlled. This type of valve mainly consists of a valve body, a diaphragm and a pneumatic actuator. The valve body is a closed housing, the diaphragm is an elastic membrane that can be bent, and the pneumatic actuator is a device that controls the movement of the diaphragm.

When the pneumatic actuator receives a signal, it drives the diaphragm to move, causing the valve to open or close. Since the diaphragm is isolated from the fluid medium, it can effectively prevent fluid leakage and contamination. In addition, precise control and regulation can be achieved due to the high control accuracy of pneumatic actuators.

Pneumatic head tank bottom diaphragm valve is a special type of valve, which has the advantages of simple structure, convenient operation and good sealing performance, and is widely used in chemical, pharmaceutical and other occasions that need to control the flow of gas or liquid.
