Motorized butterfly valve and manual butterfly valve difference

The difference between motorized butterfly valves and manual butterfly valves is that one is electrically driven and one is manually operated, in addition, they are also different in function and use.

Motorized butterfly valve

The motorized butterfly valve is composed of an motorized actuator and a butterfly valve. There are two control modes: switch and adjustment. The opening and closing of the butterfly valve are driven by the rotation of the electric actuator. At the same time, the motorized butterfly valve also has a manual operation function, which is convenient to switch the butterfly valve by manual operation in the event of power failure.

Applications of motorized butterfly valves include canning/bottling systems, beer brewing and beverage technology, chemical industry, fluid mixing units, food, industrial concrete and cement industries, vacuum technology, water treatment units, laundry rooms, medical equipment, boiler feed water, process control.

Manual butterfly valve

Manual butterfly valve as the name suggests is the need for manual operation to achieve the butterfly valve open or close, in view of this mode of operation, manual butterfly valve is not suitable for installation at high altitude, or dangerous working conditions.

The most important point of the installation environment of the manual butterfly valve is to facilitate manual operation, the valve installation position must be convenient for personnel's daily operation and future maintenance, and the best position for manual valve installation is about 1.2 meters of the operating floor.

Under normal circumstances, manual butterfly valves are suitable for: 1. Require throttling, regulating and controlling flow; 2. Mud medium and medium containing solid particles; 3. Occasions requiring short valve structure length; 4. Occasions requiring fast opening and closing speed; 5. Occasions with small pressure difference.
