Series 80-TP Towniprene® Lined Knife Gate Valve
Townley has created a unique line of Series 80-TP Towniprene® Urethane Lined Knife Gate Valves designed to provide an excellent lifetime of service in fine slurry found in mining beneficiation, tailings handling, and Coal-fired FGD limestone slurry circuits. These rugged one-piece cast ductile iron body, urethane lined valves provide absolute sealing when closed because of the precision-machined radius on the edge of the blade and the compression seal at the apex. Fine media does not adhere to the unique fluorocarbon treated blade and maintenance can change out the bottom portion of the valve in the field. Townley can recommend and install any actuation you desire to meet your requirements in a quick-turn fashion.
