A diaphragm is a special type of valve commonly used in chemical, pharmaceutical and other applications where gas or liquid flow needs to be controlled. The valve is mainly composed of a valve body, a diaphragm and a pneumatic actuator. The valve body is a closed shell, the diaphragm is an elastic film that can be bent, and the pneumatic actuator is a device that can control the movement of the diaphragm.
When the pneumatic actuator receives the signal, it will drive the diaphragm movement, so that the valve is opened or closed, because the diaphragm is isolated from the fluid medium, it can effectively prevent fluid leakage and pollution, in addition, because of the high control accuracy of the pneumatic actuator, it can achieve precise control and regulation.
Pneumatic tank bottom diaphragm valve has many applications in the chemical and pharmaceutical industry, such as in the fermenter, reactor, storage tank and other equipment to control the flow of gas, because of its simple structure, easy operation, good sealing performance and other advantages, pneumatic head tank bottom diaphragm valve has become a common valve in these industries.
Pneumatic head tank bottom diaphragm valve is a special type of valve, with simple structure, convenient, good sealing performance and other advantages, widely used in chemical, pharmaceutical and other need to control the flow of gas or liquid occasions.
Through 360° rotary handle, the ball body which have transfixion cavity and precise manufacture will open or close the valve, reaching the purpose of controlling the flow rate of medium.
There are various standard valve series can be supplied, they are the DIN standard series,3A standard series, SMS , ISO/IDF , BS/RJT , ASME/BPE standard etc. The constitute elements of ball valve always included: one handle, one ball body with transfixion cavity, valve body, valve central spindle and spindle shaft seal. The specification of ball valve series are welded ball valve, clamped ball valve, threaded ball valve etc.
