MA16 Series

Pneumatic diaphragm actuators

Our line of Saf-T-Gard actuators includes MA16 Series diaphragm actuators, which incorporate features from our field-proven products, combined with our industry-leading, innovative technology. Particular attention has been given to safety, ease of maintenance, and cost of manufacturing. The Cameron pneumatic diaphragm actuator series can be used with all manufacturers' gate valves in nominal sizes from 2 to 5 in.

The MA16 Series doubles the area affected by applied control pressure. Its simple design and operating principle make this diaphragm actuator inherently trouble-free, avoiding most of the problems such as galling misalignment, distortion, and O-ring failures commonly associated with piston-type actuators. The Saf-T-Gard diaphragm actuators are interchangeable with other models in the product line, which reduces the number of spare parts typically required for maintenance.
