Type Description

The Type 2051 pneumatic rotary actuators are low maintenance single or double acting pneumatic linear piston actuators where linear movement of the piston due to the pilot air causes a 90º rotation of the connected valve. Actuator-valve coupling is made via a universal ISO 5211 mechanical interface. The status of ball or butterfly valve can be monitored via the feedback switches of 1061. Moreover the actuator can be used as modulating control actuator by the addition of Bürkert’s range of Side Control positioners 8792/3.

  • Modular program for mounting of quarter turn valves such as ball valves and butterfly valves
  • NAMUR and ISO 5211 interfaces
  • Position feedback with Type 1061 possible (also for Ex-applications)
  • SideControl Positioner ready - Type 8792/3
  • ATEX 2014/34/EU

For selecting the correct product please refer to the technical data, images and notes for proper use according to the data sheet.

Know Your Pneumatics: Rotary Actuator Basics

Rack and pinion rotary actuators use a cylinder piston attached to a rack gear. When actuated, the piston and rack move in a linear fashion rotating the pinion gear and output shaft. A double rack unit utilizes two racks on opposite sides of the pinion gear, in effect, doubling the output torque of the unit. Parker's VRS/VRA Series is an example of a rack and pinion rotary actuator that converts linear motion via a rack and pinion drive to a male or female output shaft.


Know Your Pneumatics - Rotary Actuator Basics - Pro-PRN Series Vane Actuator-Pneumatic Division Europe-Parker Hannifin CorporationVane actuators have a cylindrical chamber in which a vane is mounted on a central shaft. Air pressure applied on one side of the vane forces it to rotate until it reaches the end of the stroke. Alternatively, air pressure from the opposite side of the vane drives the shaft in the opposite direction until it reaches the end of stroke. In a single vane style, the rotary motion is typically limited to 280 degrees. In a double vane style, the motion is typically 90 or 100 degrees, offering less rotational range with double the force of the single vane construction. Our PRO-PRN Series is an example of a vane actuator available in 9 sizes in single or double vane versions.

Rotary actuators can often be overlooked in the specification process as common pneumatic cylinders are specified with a pivot arm to achieve the necessary rotary motion. However, rotary actuators have the potential to greatly simplify applications because they are self-contained components capable of supporting loads due to the internal bearing sets.

Additionally, there is no need to design and construct external pillow block bearings. Unlike piston rods exposed to airborne contaminants, rotary actuators can reduce maintenance headaches in dirty environments.
