In recent years, with the development of mechanical and electrical integration, electric valve, which is an important mechanical products ushered in an unprecedented market. Huge market demand for electric valve requirements are also getting higher and higher. Compared with the traditional manual valve and pneumatic valve, the movement is more energy saving, more secure and reliable, in the environmental protection and security of the increasingly high voice today, electric valve is indispensable.
Valve in the industrial process, is mainly used to control the flow and flow of various fluids, such as water, oil, chemical liquid, etc., based on the parameters of temperature, pressure and flow, etc.. The control valve commonly used in the plant has a pressure relief valve, pneumatic fixed temperature valve, solenoid valve constant temperature system, proportional control valve constant temperature system, temperature control valve and 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 structure, the failure rate, credit and service manufacturers customer service and other factors, to achieve economic and practical purposes.
On the product itself, due to the electric valve with easy assembly, low failure rate, and in line with the needs of the industry the advantages of automation, the industry is more cost-effective choice. Because the use of conventional pneumatic valve, inevitably a piping, solenoid valve and the compressor can, while the electric motor-driven valve is easy to install, and electric valves installed with the original factory lines can be controlled, can save other costs. In addition, the motor drive open and close more smoothly, without excessive momentum shortcomings, failures can be substantially reduced.
