BI-TORQ Valve Automation offers a full line of electric actuators with torque ranges from 100 to 20,000 inch-pounds, in 115VAC, 230VAC, 24VAC, 12VDC and 24VDC voltages. All electric actuators are available for modulating (4-20mA control) or on-off service. Fully adjustable limit switches allow for fine control of on-off positions.

Options for NEMA 4, 4X and 7 enclosures provide flexibility for a variety of environments and applications. ISO mounting and a double star output shaft allow for direct mounting to a variety of quarter turn valves. We can provide a complete automated assembly with our InstruPak ball valves and butterfly valves, or retrofit onto an existing valve with our customized mounting hardware.

What Is a Valve Actuator?

Valve actuators are a vital component in the modern day chemical, food and beverage, oil and gas, and electric power industries. These devices allow operators to remotely adjust the position of various types of valves. This ability is crucial, as the manual operation of valves in large industrial plants can be time-consuming and impractical.

Electric actuators are mechanical devices that convert electrical energy into a form of mechanical motion that drives the movement of the valve. The motion generated by the electrical actuator can either be rotary (electric quarter or multi-turn actuators) or linear (electric linear actuators).

The primary component of these actuators is the heavy-duty motor which rotates when energized. Other structural elements such as gears, bearings, and shafts typically work together with the motor to produce the desired valve motion.

BI-TORQ’s line of electric actuators is specially designed for complete control over quarter-turn valves, ball, butterfly, and plug valves.

Benefits Of Electric Valve Actuators

Electric actuators offer a wide range of advantages over their pneumatic and hydraulic counterparts.

  • Precise
    The most significant benefit of these actuators is their superior accuracy and precise positioning performance. Through the use of programmable encoders and controllers, electric actuators can easily achieve precise intermediate positioning with millimeter accuracy. These actuators are best suited for applications where flow needs to be throttled as opposed to simply being switched on or off. Furthermore, the programmable nature of electric actuators permits complete control over valve motion parameters such as velocity, position, and cycle times.
  • Clean
    In addition to its overall accuracy, electric actuators are also considered to be cleaner and safer for the environment. Since their operation does not involve any fluids, leaks are eliminated, lowering the possibility of environmental contamination. Electric actuators are also quieter, making them ideal in noise-sensitive environments.
  • Low maintenance
    Although the initial cost may be slightly higher than other types of actuators, electric actuators require significantly less maintenance and part replacement, which results in an overall lower cost over the lifetime of the device.
