overview of Electric cutting Ball Valve products

Anshan AEN.TECH ZAJO electric cut-off ball valve adopts O type ball core structure, so it is also called electric O type ball valve. The electric cutting ball valve has the advantages of compact structure, small volume, light weight, close distance between the valve seat and the end flange, less material retention, superior sealing performance and so on. The electric switch ball valve is suitable for the two position cut off situation. The connection between the valve and the actuator adopts the direct connection mode, the electric actuator does not need to be equipped with servo amplifier, and the 220 VAC power supply can be input to control the operation. Electric cutting ball valve has the advantages of simple connection, compact structure, small size, light weight, low resistance, stable and reliable operation. Electric O ball valve and electric cut-off ball valve are widely used in chemical, petroleum, pharmaceutical, light industry and other industries.

The unique electric brake circuit is adopted, thus the positioning accuracy is high, the actuating mechanism is sensitive, the starting and stopping are quick, and the operation is stable. At the same time, it has the characteristics of anti - interference, anti-surge voltage and strong anti-breakdown capability.
It is suitable for regulating circuits with frequent movements. when the connection duration is 25 %, the number of movements per hour can reach 630 - 1200.
