Pneumatic diaphragm valve
A pneumatic diaphragm valve uses a valve body with a flexible diaphragm closure and an air-powered drive. This identity does not imply hygienic construction, diaphragm material, supply pressure, or a particular failure action. Diaphragm compatibility, travel, required force, cycle frequency, fluid retention or drainage, and actuator attachment must come from product documentation.
