A pneumatic head Tank Bottom Diaphragm Valve is a special type of valve commonly used in chemical, pharmaceutical, and other situations where the flow of gases or liquids needs to be controlled. This valve is mainly composed of a valve body, diaphragm and 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 can control the movement of the diaphragm.


When the pneumatic actuator receives a signal, it drives the diaphragm to move, allowing the valve to open or close. Since the diaphragm is isolated from the fluid medium, it is effective in preventing fluid leakage and contamination. Additionally, pneumatic actuators allow for precise control and adjustment due to their high control accuracy.


Pneumatic head tank bottom diaphragm valves have many applications in the chemical and pharmaceutical industries, such as controlling the flow of gases in equipment such as fermenters, reactors, storage tanks, etc. Due to its advantages such as simple structure, easy operation, and good sealing performance, pneumatic head tank bottom diaphragm valves have become a common valve in these industries.


The pneumatic head tank bottom diaphragm valve is a special type of valve with the advantages of simple structure, easy operation, and good sealing performance, and is widely used in chemical, pharmaceutical, and other occasions where the flow of gas or liquid needs to be controlled.
