A motor operated valve, which is even known as the MOV, is the valves that are actuated by the electric motors. They are generally the large sized valves that are being put in use in different operational work. It is basically due to the large size of the valve actuators, an electric motor is required for both the opening and closing of the valve. The different types of available Motor operated on the basis of how the valves could be actually opened and closed and for what applications it is to be actually used for. The different types of Motor operated valve actuator is dependent on the desired variety of the flowing control which one desires of from the automated valves.
Types of Motor Operated Valve
• Open and close valve - These valves are basically used as the on and off valves for turning the flow on or off as per requirement. The primary intention is not just limited to the precise control of the flow. The motor is being used for the opening and closing task of the heavy actuators of the large sized valves. Some of the application areas include pump discharge or suction valves, drum vent valves, boiler feed water isolation valves, product line valves, etc.
• Inching valves - This particular valves offer comparatively more précised control flow when compared to the on and off valves. The motorized actuator facilitates the gradual opening and closing of the valve, enabling a higher control degree over the flow.
• Precision flow valves - Now, the precision flow valves enable flow control even better than the inching valve. While the inching valve operates in the various step configuration of the controller, the precision flow valves help with the continuous flow control. Moreover, the use of proper feedback could be used directly from the field to the controller, which is not found in the other motor operated valves.
A pneumatic actuated ball valve is even used for the valve automation mechanism are available in all the material type such as brass, stainless steel, and PVC.
