Heavy one-piece Yoke
Provides maximum strength and rigidity.

Diaphragm Cases
Pressed steel upper and lower cases combine lightness, high mechanical strength and adequate protection in the event of severe over pressurization.

Thrust Capability
Two actuator types and six sizes provide a wide range of application.

Diaphragm
Molded elastomer with fabric insert for strength, long life and high sensitivity.

Linearity
The molded diaphragm and deep cases minimize area change and produce a linear relationship between travel and air pressure.
