Linear Actuators for Industrial Applications
۳۲۷۷ – Pneumatic Diaphragm Actuator (Int. Positioner Mount)
Size: 120 to 750cm2
Rated Travel: 7.5 to 30 mm
Available Thrust: 0.72 to 27 kN
Options: Handwheel, Travel Stop, Fire Lock
The Type 3274 electro-pneumatic actuator is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from the micro-flow valves to 6″ globe control valves. The thrust output of the actuator for both extending stem and retracting stem is limited to a maximum depending on the exact model.

Features & Benefits
- Integral attachment of accessories that eliminates tubing by providing a single pneumatic connection between the positioner and limit switch as well as providing an exact and firm mechanical connection that shields linkage
- Field-reversible, multi-spring diaphragm actuator allows changing of fail-safe action.
- Multi-spring actuator offers uniform application of actuator forces to control valve as well as reduces height and weight of valve.
- Actuator, together with positioner, can be rotated a complete 360 to allow for ease of local operation regardless of valve orientation.
- Rolling diaphragm offers increased precision and reduced hysteresis compared to stretching diaphragms.
