Samson 3277 Pneumatic Actuator

Samson 3277 pneumatic actuator provides customers with switching and throttling service applications. Samson 3277 pneumatic actuator is linear motion. The rated stroke of the Samson 3277 pneumatic actuator is 7.5mm to 30mm. Samson 3277 pneumatic actuators are commonly used in petrochemical, refining, chemical, and other industries. Samson 3277 pneumatic actuators with an effective membrane area of 240, 350, or 700 square meters are mainly installed on the control valves of the 240, 250, and 280 series.

Product Features

Samson 3277 pneumatic actuator rolling diaphragm actuator with an integrated accessory attachment area is designed for all industrial applications. Samson 3277 pneumatic actuator is a linear motion device ideal for valve sizes ranging from micro-flow valves to 4″ globe control valves.
The thrust force of Samson 3277 pneumatic 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.

Samson 3277 pneumatic actuator
Single-acting linear actuator with rolling diaphragm and innerspring
Diaphragm area 120 to 750 cm
Direct connection of attachments on the additional yoke with hidden stroke cutting
Low overall height
High-speed impulse
Low friction
Change the range of the table by changing the number of springs or their compression.
No special tools are required to change the range of the worktable or change the direction of operation (handwheels can also be used)

Samson 3277 pneumatic actuator
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.
The Rolling diaphragm offers increased precision and reduced hysteresis compared to stretching diaphragms.
