Electrictype 0 cutting ball with the introduction of the Unic series ofelectric devices and 0-ball composition, with excellent sealing, usuallyfor sealing demanding applications, widely used in chemical, oil,paper, steel and other industrial sector control pipeline The cuttingand circulation of the media and other purposes.
Comparedwith the ordinary electric ball asked, has the following specialadvantages: compact, fine small, light weight, easy maintenance, flowresistance is almost zero.0-typeball can also be asked and Nucom electronic electric home appliances ordomestic DKJ-Z-type electric actuator supporting the ball to ask 0 alsohas a regulatory role.
