Lined Diaphragm Valve
Lined Diaphragm Valve
Chemoil Advance Technology supplies Lined Diaphragm Valves from recognized manufacturers for reliable flow isolation and control in industrial applications involving corrosive and chemically aggressive process media. The lined construction provides a protective barrier between the process fluid and selected valve components, helping improve corrosion resistance and material compatibility.
A diaphragm valve uses a flexible diaphragm to control the flow passage, separating the operating mechanism from the process medium. This design can be particularly useful for applications where clean operation, reliable isolation and reduced exposure of internal operating components to the process fluid are important.

PFA Lined Diaphragm Valve Handwheel Operated
Our products utilize triple-layer Diaphragms to avoid failure of Diaphragm due to permeation, especially for chlorine application. They are anchored with dovetail grooves making the valve suitable for both pressure and vacuum applications. We offer all metal components in investment castings, ensuring intact and homogeneous lining and having an overall even design.

PFA Lined Diaphragm Valve Pneumatic Operated
Our easy to use, pneumatically operated valves are ideal for industrial and corrosive duties. Each is certified 100% leak-tight operation with low maintenance. They are the best in performance in regards to throttling and flow control applications.
