Product Description

Pneumatic Actuator Type 3277

         The Type 3277 Pneumatic Actuators are diaphragm actuatorscontaining a rolling diaphragm and multiple, internal springs.Their design and operating principle corresponds to that of the Type 3271 Pneumatic Actuator (see Data Sheet T 8310 EN for details). The bottom diaphragm case is affixed to the yoke, on which an optional positioner can be attached (pneumatic or electropneumatic models available).

Specification

Advantages of direct attachment:

 Interference fit providing exact mechanical connection;
no alteration of adjustment during shipping
• Travel linkage protected against unwanted contact and external influences; corresponds to the accident prevention requirements of UVV (VBG 5)
• Simple air connection between the actuator and the
positioner

• Low overall height
• Powerful thrusts
• High speeds of response
• Various bench ranges (signal pressure ranges) possible
• No special tools required to reverse the actuator action and
modify the bench range

With the Type 3277-5 Pneumatic Actuator for Integral Positioner Attachment, the positioner output pressure pst is introduced as loading pressure either to the top or bottom diaphragm chamber, resp. independent of the operating direction
of the actuator and positioner. No additional piping is necessary. Only the changeover plate needs to be set correspondingly
