Diaphragm Valves are a type of valves used to control and balance the pressure and volume in a fluid flow system. The valves use diaphragms instead of gates, needles or discs to control the flow. The Diaphragm Check Valves have a vacuum chamber that can hold the liquid with a diaphragm which controls the volume of the chamber. The chamber gets the fluid from the inlet of the pipe system. The diaphragm of the Diaphragm Control Valves is attached to a threaded stem and handle. As the handle turns, the stem lowers or raises. This brings the diaphragm up and down increasing or decreasing the volume and the pressure is inversely proportional to the volume at any given temperature. The Diaphragm Type Float Operated Valves use a float to control the movement of the diaphragm. Once the pressure is controlled and regulated, the fluid is then allowed to move through the outlet.

The system is very efficient to be operated automatically to keep the pressure at one certain level. Chemical, pharmaceutical, food processing and other highly sensitive applications require the pressure to be maintained at a certain level. These valves can help achieve the targeted pressure either manually or automatically. Some valves such as the Diaphragm Solenoid Valves use solenoid diaphragms and parts for operation under corrosive conditions. The valve body could be made up of different materials and the sizes and dimensions can vary according to the different standards.
