Diaphragm Valve

Nilon Diaphragm Valve a suitable for positive pressure and high vacuum application. The diaphragm isolates the operating mechanism in the bonnet from the fluid in the pipeline. This achieves two objectives one it ensures purity of the line fluid and two, the operating mechanism is not corroded by the fluid and is therefore permanently protected against chemical attack. Maintenance of these valves is very simple. By dismantling the bonnet from the body, the entire trim assembly can be taken out for maintenance and the body remains in the pipeline. Thus the design permits online maintenance and saves time and energy.
