Pneumatic Actuators


Type 2051 - Pneumatic rotary actuator


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

Type 2052 - Pneumatic rotary actuator


The Type 2052 pneumatic rotary actuator consists of a single or double-acting pneumatic linear piston actuator with an internal coupling to a rotary joint and a universal mechanical interface acc. to ISO 5211. The actuator shaft is rotated 90º via the coupling by the linear movement of the piston due to the compressive force of the pilot air or the force of the return springs. This rotation movement can be utilised for respective actuators such as ball valves, flaps, etc. The actuator has an optical display for the rotation position. The actuator is cataphoresis and Rilsan coated internally and externally which makes it very corrosion resistant and maintenance free.

  • Modular program for mounting to armatures such as ball valves and butterfly valves
  • NAMUR and ISO 5211 interfaces
  • Position feedbacks, also Ex-versions
  • Mounting of SIDE control positioner

  •  Visual indicator
  •  Open and closed end of travel adjustment
  •  Mounting to Namur Standards
  •  HVAC Applications 

Series 84, stainless steel with 0°-90° rotation, 22Nm to 160Nm.


The series 84 presents the same compact design and the same technical features of the series 82, with the exception of construction material; the series 84 of Valbia is, in fact, manufactured using body, and caps and pinion in stainless steel and it is available in 5 models.

  • Stainless Steel Body
  • ATEX II 2GD T6 approved
  • Rack and Pinion design
  • Models 52  -  100 (Currently 5 sizes available)
  • Visual indicator
  • Open and closed end of travel adjustment
  • Mounting to Namur Standards
  • Aggressive Environments
  • Shipping / Off Shore
  • Chemical Applications

Special version Nickel plated, PTFE coating


Nickel plated: process developed for the actuator protection in harsh environments through the application of an uniform coating over the entire surface, in order to give the actuator a higher  protection against corrosion. Suitable also in the pharmaceutical and food industries and in all those sectors where alkaline solutions and cleaning agents are used.
 
With PTFE coating: coating applied by spray technique over the entire actuator surface and cured in the oven. 
It provides excellent corrosion protection to marine environments, environments with high temperatures and ensures great antistick properties; it is also used in a wide range of industrial applications.
 
  • High temperature: to withstand temperatures up to 150°C.
  • Low temperature: for applications that require the use down to -40°C.
  • With 303 stainless steel pinion.
