**[Motor Operated Valves ] ** Motor Operated Valves (MOVs) are essential components in industrial automation and process control systems. Their ability to precisely regulate fluid flow under the control of instrumentation devices makes them indispensable for a wide range of applications. Understanding the operational principles and instrumentation aspects of MOVs is crucial for engineers and technicians involved in their design, installation, maintenance, and operation. >>From an instrumentation perspective, MOVs play a vital role in process control systems. They are often integrated with various instrumentation devices to monitor and regulate process parameters such as flow rate, pressure, temperature, and level. 1. Positioners: Positioners are often employed to ensure precise valve positioning, especially for proportional MOVs. They receive a signal from the control system and adjust the actuator's air pressure accordingly, achieving accurate valve positioning. 2. Limit Switches: Limit switches are safety devices that prevent the valve from exceeding its maximum or minimum travel limits, protecting the valve and the associated piping system from damage. 3. Solenoid Valves: Solenoid valves are used to control the flow of air or hydraulic fluid to the actuator, enabling remote operation of the MOV.
