The MSD-Ⅱ/ III is a pneumatic, spring-opposed diaphragm actuator operating from plant air. Excellent long- term accuracy and reliability is achieved through the use of multiple springs in the actuator. The rugged one-piece yoke, the pressed steel diaphragm case and the special nylon reinforced diaphragm provide dependable, high thrust performance. Additionally, the precision formed diaphragm eliminates friction and reduces variations in the effective area during operation which, in turn, results in exceptional linearity. An optional top or middle-mounted manual override is available on both direct and reverse acting actuators. Six different sizes of the MSD-Ⅱ/ III actuators with various accessories can virtually satisfy all application requirements.

Features

Excellent performance
As a multi-spring type, Operation is precise and repeatability is excellent Minimizing the hysteresis error.

Fast Response
The pressure-tight chamber to which air pressure is connected has a small volume for fast response.

Rugged Construction
All parts are engineered and tested for long life under millions of cycles.
