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.
