Kempe’s WearStar butterfly valve is engineered for superior performance in abrasive and corrosive environments. It features a polyurethane seat and a tungsten carbide-coated disc, providing exceptional durability and wear resistance.

Anti blow-out proof stem design, suitable for higher pressure and vacuum applications due to the cartridge seat design. High flow capacity and sufficient strength due to the streamlined disc design, raise seating face eliminates the need for flange gaskets. ISO 5211 top flange suitable for direct mount actuation. Ingress seal prevents contaminants from entering the shaft area.

We supply multiple actuation options
