The motor operated valves (MOV) is an important element of the plant and pipe system. These valves are generally large and are used for different applications such as pump discharge, etc. The control valves operated by motor are often called on / off valves since the motors serve to open or completely close the valves in the pipes. For example, cooling water lines, process piping where fluid control is not required, motor operated valves can be used to completely allow or completely stop the flow of fluid. These valves are not used for throttling purposes since they mainly serve On-Off service applications.

The valves operated by motor can be of various types, e.g. Gate / Ball / Butterfly etc. with actuator control. The design of engines and valves may be different. An electric motor is mounted on the valve and geared to the valve stem so that when the engine is running, the valve will open or close. For this MOV, a motor operated with actuator control is required from the local panel or from the control room. There is a requirement for coordination between the pipeline, electrical, instrumentation, process and supplier engineers for the design and acquisition of such motor-operated valves.

The VALVOMEX Motor Operated Valves (MOV) family of valves are an important item of Plant & Piping system. These valves are generally of large size and are used for different applications such as pump discharge etc. Motor Operated Valves are often called as On-Off valves as the motors serve the purpose of fully opening or fully closing valves in pipelines. For example, cooling water lines, process pipelines where regulation of fluid is not required, motor operated valves can be used to fully allow or fully stop the fluid flow. These valves are not used for throttling or precise control / regulation purposes as they serve mainly On-Off service application.

Motor operated valves can be of various types e.g. Gate/ Ball/ Butterfly etc. with actuator control. Design of Motors and valves is fully integrated by VALVOMEX’s Valve Engineering Unit that precisely engineer all items case-by-case.

An electric motor is mounted on the valve and geared to the valve stem so that when the motor operates the valve will open or close. For MOV, motor operation with actuator local control from local panel or from control room is foreseen. Our valve engineers coordinate with end user Piping-Electrical-Instrumentation-Process engineers and for design and engineering of such motor operated valves.

Applications of motor operated valves

– Whenever frequent operation is required.

– Valves located in remote, inaccessible or dangerous places.

The motorized control valve / motor operated valves are generally for full opening and full closing applications. However, there are places where they are also used for position control.
