Top Supplier Electric Butterfly Valve Actuator

Electric butterfly valves control the flow of process media by moving a round disc to an open or closed position. When the disc is open it is held parallel to the pipes, and media is permitted to flow past it on either side and into the next section of pipe.

Specification of this Top Supplier Electric Butterfly Valve Actuator

Electric butterfly valves control the flow of process media by moving a round disc to an open or closed position. When the disc is open it is held parallel to the pipes, and media is permitted to flow past it on either side and into the next section of pipe. When electric butterfly valves are in the closed position, they are perpendicular to the pipe, and create a seal that does not permit any materials from flowing through that pipe section. The disc of an electric butterfly valve is attached to a shaft, which is able to turn the disc and thus open or close possible flow steams.

Whether electric butterfly valves are in the open or closed position, they will have an impact on the flow of substances within the pipeline. A closed butterfly valve will stop the flow completely, and an open butterfly valve will still reduce the volume of the flow, as the valve is still a presence within the pipeline that the substances must flow past. These aspects of electric butterfly valves need to be considered before installation, to ensure that the pressure change that is created is not hindering overall factory functions and production.

Electric butterfly valves can also be operated to partially open positions, which can limit the flow of a substance without cutting it off completely. This throttling ability could be incredibly useful for a company's operations. It gives the company a great degree of control over processing while it is taking place. If too much gas or liquid ends up in a certain portion of the pipeline, the electric butterfly valves in that area can be quickly controlled to move to new positions that favorably regulate the flow amount.

Product advantage of this Top Supplier Electric Butterfly Valve Actuator

Electric butterfly valve is composed of electric actuator and sanitary butterfly valve. So it has the advantages of easy operation and simple structure. It’s also widely used in chemical, pharmaceutical and other industries. And because of the help of the electric actuator, the development of butterfly valve reaches a new level. The mechanism of electric butterfly valve: the electric device drives the valve stem, which makes the butterfly plate rotate 90 degrees to achieve the opening and closing of the valve.

The mechanism of electric actuator is actually very simple. Just like the razor we use in our daily lives, the energy source is electric power. Electric power leads to the operation of the valve plate, so as to achieve the goal of opening and closing valves and connecting or shutting-off fluid. The electric actuator of electric butterfly valve can be divided into switch type and regulation type. The switch type electric butterfly valve is to play the role of switching while the regulation type electric butterfly valve is to play the role of regulating flow. The regulation type valve can accurately regulate the flow to one-thousandth degree. It’s also a kind of pricey valve. Valve is a kind of device that is installed in the pipeline. It’s a bit unrealistic to check the state of the switch on field. That’s why feedback signal exists. The regulation type itself has a feedback signal while the switch-type can allow users to decide whether to install the feedback signal.
