The application of electric automatic control valve plays indispensable role in operational efficiency and energy consumption saving, the manual valve and pneumatic valve used in traditional industry are inferior to electric control valve in installation cost and efficiency.
　　On the product itself, for the electric valve has the advantages of easy assembly, low failure and meet automation demand, is the reasonable choice for operator. The general traditional pneumatic valve and hydraulic control valve also need tubing, solenoid and compressor, but the electric valve is driven with motor, easy to install, and the installation only needs original automatic control circuit, could greatly save the cost. Besides, the motor drive could keep smooth open and close, without instant excessive momentum, greatly reduce the failure rate.
　　As the industry concerned indicated that most regulating valve is used to control the process and flow of various fluids, such as water, oil, and chemical liquid etc….depends on temperature, pressure and flow. But control valve that frequently-used by factory are compression release valve, pneumatic constant temperature valve, solenoid valve constant temperature system, proportional control valve constant temperature system, temperature control valve. When select various automation valve, shall consider the type and precision of heat machine, quality, pressure drop, flow of breathing control valve, including structure, failure rate, credit and after-sale service, as to reach purpose of economic and practical.?
