Easy control valve solutions: process control optimization through fail-safe vane actuators

摘要

Optimal process control depends on multiple components working properly. However, positioners, actuators, and valves are the only pieces of equipment that move, which means they're often the weak link of the loop. This movement causes problems such as hysteresis, stiction, and increased response time, reducing the overall control loop performance. Proper actuator selection is necessary to address these problems, because actuators are at the center of every moving part of the control valve. Recent developments in fail-safe vane actuators are enhancing process control with rotary valves and should be closely followed in the market.
