3271 – Pneumatic Diaphragm Actuator
The Type 3271 pneumatic rolling diaphragm 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 large 20″+ globe control valves. The thrust force of the actuator depends on the actuator area, pneumatic supply pressure, spring stiffness, distance traveled, initial compression of the spring, the number of springs internal to the actuator, etc.
Size: 120 to 2x2800cm2
Rated Travel: 7.5 to 160 mm
Available Thrust: 0.72 to 151.2 kN
Options: Handwheel, Travel Stop, Fire Lock

3273 – Handwheel
The Type 3273 is a manual operator hand wheel actuator for attachment to linear motion control valves. This 3273 actuator is offered in two versions: top mounted wheel as well as side mounted wheel depending on the valve size and require force.
Orientation: Top or Side Mount
Rated Travel: 15 to 120 mm
Available Thrust: 0 to 150 kN
Options: Gear Operator
3274 – Electro-Hydraulic Actuator
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.
Application: Electrohydraulic Actuator for Plant Engineering and HVAC
Rated Travel: 15 to 30 mm
Available Thrust: 0.5 to 7.7 kN
Options: Fail Safe Action, Electric or Mechanical Override
3277 – Pneumatic Diaphragm Actuator (Int. Positioner Mount)
The Type 3277 pneumatic rolling diaphragm actuator with an integrated accessory attachment area is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from the micro-flow valves to 4″ globe control valves.
The thrust force of the actuator depends on the actuator area, pneumatic supply pressure, spring stiffness, distance traveled, initial compression of the spring, the number of springs internal to the actuator, etc.
Size: 120 to 750cm2
Rated Travel: 7.5 to 30 mm
Available Thrust: 0.72 to 27 kN
Options: Handwheel, Travel Stop, Fire Lock

3372 – Pneumatic Diaphragm Actuator (for V2001 & HVAC)
The Type 3372 pneumatic diaphragm actuator is designed for use with V2001 and 3522 control valves for light industrial applications with integral I/P converter or direction attachment of electro-pneumatic 3725 positioner.
This actuator is a linear motion device ideal for valve sizes ranging from 1/2″ to 4″ globe control valves. The thrust force of the actuator depends on the actuator area, pneumatic supply pressure, spring stiffness, distance traveled, initial compression of the spring, the number of springs internal to the actuator, etc.
Size: 120 and 350cm2
Rated Travel: 15 to 30 mm
Available Thrust: 0.7 to 11.55 kN
Options: Integrated Positioner or Direct Mount
3374 – Electric Actuator
The Type 3374 electric actuator is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from 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.
Application: Electric Actuator for Plant Engineering and HVAC
Rated Travel: 15 to 30 mm
Available Thrust: Upto 2.5 kN
Options: Integrated Positioner, Limit Switches, Fail Safe Action
3379 – Pneumatic Piston Actuator (Hygienic & Aseptic)
The Type 3379 Pneumatic actuator with spring-return mechanism is designed to be used in conjunction with a control valve suitable for the hygienic application of food and beverage as well as life sciences industries. This actuator is design with a smooth stainless steel surface that allows for easy cleaning. All moving parts are located inside the housing for improved process safety.
The design includes a visual indicator of valve positon as well as internal air routing to prevent air or water from entering the device.
Additional components for controlling the valve movement, such as a 3724 positioner or 4740 limit switch, can be internally incorporated into the actuator housing.
