A common misconception in our industry is that actuating a valve is as simple as putting the most cost-efficient actuator on top of your valve of choice, but the process is much more complicated than that. Selecting the correct actuator for the size and purpose of the valve is key, but it’s only the first step. If the actuator isn’t sized by a knowledgeable and technically trained expert, the results can be disastrous and/or expensive.
When sizing an automated valve, the actuator must operate properly when on demand, especially on Emergency Shutdown Valves (ESDVs). With constantly increasing safety demands, more actuator buyers are taking the extra step of requesting actuator sizing documentation.
