3277 - Pneumatic diaphragm actuator type

The Type 3277 pneumatic rolling diaphragm actuator with direction accessory attachment area is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from 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, number of springs internal to the actuator, etc.
