Ball Valves and Butterfly Valves

Valves that open and close the pipe by rotating the closing device (bored through ball resp. disc plate) horizontally in relation to the flow direction.
To open and close the pipe the ball valve mechanism uses a bored through ball which is rotated horizontally by 90° in relation to the flow direction.
To open and close the pipe butterfly valves use a disc rotated horizontally through 90° in relation to the flow direction.
Ball valves that are especially designed for a pressure rating up to PN 100.
