Electric Ball valve mainly by the electric actuator and ball valve composition, the cock body for the ball, with the rotation of 90 degrees action. Electric Ball Valve can not only throttle, cut-off, cut-off, on-off, transfer of good products, or flow control system commonly used components. It has the characteristics of pressure resistance, temperature resistance, corrosion resistance, small flow resistance, long service life, wide application range and so on. Electric Ball Valve working principle: Electric Ball valve mainly depends on electric actuator current/voltage regulation to operate the ball valve. Electric actuator input and output signal 4-20mA (1 ~ 5V or 0 ~ 10V) and 220VAC (AC/DC24V, AC380V, etc.) power supply standard signal, motor set drive gear worm angle Torque, to control the opening and closing of the ball valve, distribution and change the direction of the flow of media or adjust the proportion of rotating spool, that is, valve opening and control fluid proportional, or percentage. ELECTRIC BALL VALVE COMMON APPLICATION: Electric Ball Valve does not need manual operation, can be wired or wireless remote control. In the process of system control, the selection of environmental factors should also be different, such as in high pressure, high temperature or low pressure, low temperature environment used in electric ball valve is different. Should pay attention to the following points: 1, for low temperature and low pressure, material does not need too much adjustment. 2, in high pressure, high temperature, high pressure materials should be used as electric ball valve materials, such as: stainless steel, alloy steel and rare special steel, such materials can withstand high pressure, high temperature. 3, electric ball valve its internal parts need to be replaced to reduce the damage to the Spool, but also conducive to the flow of media, to avoid electric ball valve coking and plug. 4, in the case of Electric Ball Valve Open, you can install a number of vibration-proof components to prevent the opening of the destruction of the electric ball valve spool internal structure.
