As the valve use is widespread, so it's role is great. For example: In a power plant valve to control the boiler and turbine operation; in petroleum, chemical production, valve control also plays a normal operation of all production equipment and processes. In other sectors as well. Nevertheless, valves comparison with other products is often overlooked. For example: When installing the equipment, people tend to focus on the main machinery equipment, but ignored the valve. This will make the whole production efficiency is reduced or discontinued, or causing all sorts of other accidents. Therefore, the valve selection, installation, use and so must be serious and responsible work.

Electric drive valve is a valve commonly driven approach, often call this form of drive means driving means for the valve actuators, valve actuators characteristics are as follows: 1) open and close rapidly, can greatly reduce the time required to open and close the valve; 2) can greatly reduce labor intensity, especially suitable for high pressure, large diameter valve; 3) suitable for installation in can not be manually operated or inaccessible location, easy to implement remote manipulation, and mounting height unrestricted; 4 ) in favor of the automation of the entire system; 5) Power than air and liquid source readily available, its cable laying and maintenance is much simpler than compressed air and hydraulic lines.
