What is an Actuator-operated Gate Valve?
A gate valve can be equipped with an actuator. This allows the valve to be operated from a location other than in the immediate vicinity of the valve.
The wedge sliding gate valve requires more force compared to other types of shut-off valves. Therefore, the most common actuator for them is an electric actuator.
For knife gate valves, due to the low torque requirement, we recommend using a pneumatic actuator because of its high closing speed.
Selection of Actuator-operated Gate Valves
We assist in selecting and sizing an actuator-operated sliding gate valve that meets the requirements of the application. We collaborate with the most common electric actuator manufacturers, such as Auma, Bernard, and Rotork.
Actuators can be equipped with additional devices or Fail-Safe functionality, whereby the actuator drives the valve to the closed position,
even if the power to the system is lost. Additionally, they can be fire protected.
