Duball DL Ceramic

Duball DL Ceramic

The NAF Duball DL Ceramic is a ball valve that is internally lined with ceramic for erosive and abrasive media. It is primarily intended for control but has a sealing class as for a shut-off valve. The valve represents a concrete result of our product philosophy which is focused on functionality, high quality and low life cycle costs, and is based on concentrating our range to a limited number of valve types, but all of them suitable for a wide variety of applications.
