Diaphragm Valves – Type 14/15/72

The Chemline diaphragm valves have service histories dating back to 1970 operating in tough chemical plant applications. They have proven internal and external corrosion resistance. This is an excellent throttling valve, and is suited for slurries or viscous liquids. Because of the self-draining design with no dead volume, it is good for sanitary and high purity applications.
