KDV BODIES
WEIR TYPE
KDV Weir Type Diaphragm Valves can be optimised for abrasive/corrosive services with a wide variety of base body materials, linings and coatings.
Body, lining & coating material selection is based on variables including: media type, temperature and pressure; frequency of thermal cycling, percentage of solids, particle size, end connections and valve size.
* Maximum continuous service temperature
