Pneumatically-Actuated Diaphragm Valves
Pneumatically-actuated diaphragm valves use compressed air to open and close the valve, start and stop the flow of chemically compatible media in a system, and have a high closing force for applications moving viscous liquids. The valve's stem is isolated from flowing media to protect it from abrasive media, such as liquids containing suspended solids and slurries.
