According to relevant industry sources, valves are mostly used in industrial processes to control the flow and flow of various fluids, such as water, oil and chemical liquids, and are based on parameters such as temperature, pressure and flow. The factory commonly used control valves are pressure reducing valve, pneumatic temperature valve, solenoid valve temperature system, proportional control valve temperature system, temperature control valve and several other types. In the selection of various types of automatic valves, should consider the type of heat engine, the required accuracy, control valve quality, pressure drop, flow and its structure, failure rate, factory credit and after-sales service and other factors in order to achieve economic and practical purposes.
According to the product itself, because the valve electric device with easy assembly, low failure rate and meet the needs of the automation industry, the industry is more cost-effective choice. Because the use of conventional pneumatic valve, inevitably have to pipe, solenoid valves and compressors to match, and the motor-driven valve is easy to install and save, and the installation of electric valve with the factory's existing automatic control circuit can save the other the costing payment. In addition, motor-driven opening and closing more smooth, no short-term impact of excessive shortcomings, the failure rate can be significantly reduced.
