What is a Pneumatic Diaphragm Valve?
The Pneumatic Diaphragm Control Valve is a kind of valve for control that's commonly used in many industries for controlling the movement of gas, liquids as well as other mediums. The valve uses compressed air (pneumatics) to move the diaphragm which functions as a seal. Simple yet efficient design is ideal to deal with a wide range of fluids such as the corrosive chemical slurries, corrosive chemicals and viscous material. How Does a Pneumatic Diaphragm Valve Work? The main component in an Pneumatic Diaphragm Control Valve is the diaphragm that can be bent and is secured between the body of the valve and the bonnet. When air pressure is applied to the diaphragm, it is forced down on the seat, shutting off the valve, stopping flow. After the pressure in the air is removed then the diaphragm returns to its position permitting the flow to continue. This type of design guarantees a secure seal. This makes pneumatic diaphragm valves...
