Haiqiao Yap Valve Manufacturing Co.] [ZAJQ electric control valve manufacturer, with large spot to ex-factory sales! Companies adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect after-sales service, welcome to buy! First, the electric control valve Product Overview ZAJQ electric control valve is suitable for two off, adjust the occasion. Valve actuator is connected to the direct connection, electric actuators built-in servo system, no need to reprovision the servo amplifier, the input 4-20mA signal and 220VAC power to control operation. ZAJQ electric control valve has a simple connection, compact structure, small size, light weight, low resistance, stable and reliable operation. ZAJQ electric control valve is typically used for sealing demanding situations, in addition to control gases, liquids, steam medium, but also suitable for controlling sewage and medium containing fibrous impurities, widely used in petroleum, chemical, metallurgy, light industry, papermaking, power plant , refrigeration and other areas of work. Electric control valve is an important valves in the petrochemical industry, long distance pipelines and other fields have a wide range of applications. Valve closure member is a perforated sphere (or part of the ball), turning ball with stem achieve the valve open or closed. Electric control valve fully closed rotate 90 ° to open, with the same specifications gate valve, globe valve comparison, ball, small size, light weight, easy pipe installation.
