Sanitary Pneumatic Diaphragm Valves

Diaphragm valves utilize pneumatic actuators to apply air pressure in operations where timing and speed are crucial for outputs. Sanitary pneumatic diaphragm valves benefit pharmaceutical companies because liquids, gases and solutions are not exposed to environmental conditions or external parts of systems. Use of a pneumatic diaphragm valve automates your process and provides repeatable outcomes.


The inherent benefit of a diaphragm valve is the separation of the process from the mechanical portion of the valve (the pneumatic actuator). This allows for less areas of contamination as well as the reduction of additional leak points. This feature, furthermore, provides is the ease of adding and changing control accessories to the pneumatic actuator. The linear action as well as the separation allows for this to be done in the field.


The actuator (opening and closing) section of Gemu sanitary pneumatic diaphragm valves are designed for low maintenance. Having the highest quality construction ranging from reinforced polymer to fully stainless steel housings. And incorporating stainless internals and high polished spindles, Gemu Pneumatic Actuators will provide a long maintenance free life cycle.
