The Typical Electric Valve Actuator Needs a Drive Control to Help it Out

The Problems

The typical electric valve actuator can have some potential problems. Many actuator designs incorporate high speed motors that don't stop immediately. This creates a situation whereby the electric valve actuator is subjected to extra stress that can cause overheating and burn the motor out.

Additionally, many an electric valve actuator that has an active loop element installed, will often have inefficient gears as well, that can wear out quickly. These inherent problems are then solved by patching the system with dead-bands. These however, can severely limit the precision of the final control component. This brings an overall reliability concern to the typical electric valve actuator.

Install a Control Drive

The electric valve actuator can not usually withstand a harsh environment and may cause system downtime. With an excellent control drive the problems of this conventional actuator can be eliminated. Control drives allow for precise and long lasting performance, in spite of changing conditions. The control drive improves performance without sticking or degrading over time.

The drive control mechanism is equipped with a complex interface panel that allows for easy calibration of electric valve actuator functions and digital communications. The drive control mechanism can do this without interfering with the actuator's control capabilities and without the need for new wiring. As well, this change over can be done locally or remotely with a hand held device.

The control drive is engineered for minimal maintenance throughout the life of the drive. This means the electric valve actuator controlled by the drive is under a stable management condition. Since the electronics of the drive are made not to drift, there is no need for recalibration when the electric valve actuator is doing its job in the field. Additionally, if you install a contact-less position sensor in the drive, it will not wear.

How the Control Drive Can Improve Performance

The mechanical design features of the control drive allow for very low maintenance, in the harshest of environments. Also, because the control drive runs on just 120 V AC power, all the problems connected with air systems are eliminated. As well, when you retrofit your electric valve actuator with a control drive it can result in immediate cost savings. Control drives for your electric valve actuators can start improving the reliability of your factory processes, as well as product quality immediately after installation. This reduces waste and improves efficiency.

You may want to consult with a sales engineer as to what exact control drive model is needed for the electric valve actuator it will be enhancing. Ask them too, if they will help plan mounting areas and hardware, determine torque, device timing, and signal connections.

This will help you save time, create an easier installation experience, and ensure the best performance for the lowest price. Remember to invest in individual cast covers to protect the components from severe weather conditions, dirt and water.

A high quality control drive is well suited for extreme environments in no small part because of these extra measures of protection. The cast covers provide rigid and tough housing for each component of the machine. Separate compartments with their own individual protection covers help to shield the major components from dirt, moisture and damage, as this is part of the overall excellent engineering of the control drives and the electric valve actuators they serve.
