Case Study Introduces a Solution to Control Valve Deadband Issues: Shape Memory Alloy Actuators

In industrial process control, maintaining precise regulation is critical, and control valves play a pivotal role in this task. However, these valves often face a common issue known as deadband—a range where input signals fail to generate any response from the valve. This can lead to inefficiencies, delayed responses, and increased wear on components, ultimately compromising system performance.

Deadband typically arises in systems that use traditional electric motorized or pneumatic actuators, where mechanical play or friction hinders precise control. The impact is especially significant in industries like natural gas, where maintaining stringent control over processes is essential for safety and operational efficiency.

Enter Shape Memory Alloy (SMA) actuators, a promising solution to these challenges. Unlike conventional actuators, SMA actuators can operate continuously at a 100% duty cycle without backlash or slop, offering high precision and responsiveness. Their ability to minimize deadband is transforming valve control in the natural gas sector, providing a more reliable and efficient alternative.
