Field Reversible
Allows air action change with no additional parts.
Multiple Spring Design
Four standard spring types achievable by varying spring quantity and placement.
Heavy One-Piece Yoke
Provides maximum strength and rigidity.
Diaphragm Cases
Pressed steel upper and lower cases combine lightness, high mechanical strength, and protection in the event of over-pressurization.
Thrust Capability
Two actuator types and four sizes provide a wide range of applications.
Diaphragm
Moulded elastomer with fabric insert for strength, long life and high sensitivity.
Linearity
The moulded rolling diaphragm and deep cases minimize area change and effects a linear relationship between travel and air pressure.
