Different butterfly valve types can achieve sufficient valve transition in many ways with the help of electric actuators apparatus that are developed under the concept of independent valve control. As a matter of fact, one of the widespread rationales in the field of electric actuators can be seen from the increasing number of butterfly valve types engine over a wide range of usage and load conditions.

At the same time, it cannot be denied that the legislation on the electric actuators fuel and emissions have become more and more strict and stringent so that more attention has been paid to making the electric actuators work in a more clean and efficient manner since a number of modern actuators operate with devices that are designed to perform shaft phase shift as well as valve timing tasks at certain operating points 2-PC Ball Valve.

Generally speaking, these shaft devices are rather reliable but their ability in assisting the electric actuators to provide valve timing variations may vary from each other, which is especially true when compared to a system that possess full valve control capabilities.

To be more specific, the valve actuation of butterfly valve types can ensure a high level of control flexibility over the engine valve phase of the electric actuators in either an independent or simultaneous manner with other valve types, which is proved to be beneficial and flexible. First and foremost, the maximum valve power can be improved at a high speed even if in some cases, the closing of the electric actuators intake valve is under high loads since the great power momentum in the intake part will push the piston forward to enter the chamber instead of being pushed out.

Another advantage of the butterfly valve types is that the working efficiency at low speed can also be improved. This is because when the butterfly valve types are not under the full work load, the intake valve types generally keep closed in order to reduce the suction force that is needed by the electric actuators.

Thus, less air needs to be compressed and less heat will be generated, leading to the higher efficiency of the entire system which can be translated into less energy consumption at low work load. What is more, possible pollution can be reduced thanks to the butterfly valve types as well since traditionally, the valve types are placed inside the engine to lower the temperature by recycling the exhaust and sending it back into the intake electric actuators valve. However, variable butterfly valve types actuation can remove the need for additional valves because there will be no overlap between the intake valve and the openings.
