Berger Lahr Servo Motors
The Berger Lahr actuator range can be used to position flaps, valves or slides with a high degree of position. Within the unit is a motor, gearbox and a control unit. Industrial Boilerhouse Supplies offers the Berger Lahr unit in model types STA and STM
STA Units
The two cams of the STA Unit serve to define the limits and the others are available for controlling external devices. Cams are continuously adjustable. Actuators of type STA are also fitted with 1 or 2 relays. The switching actions for controlling the motor are controlled via these relays. STA actuators are used to move air flaps in oil and gas burners.
Various wiring arrangements are available for connecting to standard burners.
STM Units
The STM unit are constructed in the same way as the STA units but differ in the fact that they contain no relays.
- Areas of Installation
- Air valves for oil and gas burners
- Exhaust valves on boilers
- Mixing valves
- Electrically adjustable armatures
- Slide movements
- Part turn valve actuators
- Positioning tasks in the construction of apparatus and machines
- Valves for water treatment
- Electrical engineering, open and closed loop control tasks
- Weighing and dosing technology
- Drive technology
- Control technology : Control of ball valves, flow control
