Designed and engineered for demanding applications in corrosive, sanitary and ultra-pure processes. Unique benefits in design and a wide range of options allows the Sure Seal LBF lined butterfly valve to provide superior service to the chemical and industrial market. Our ISO 9001 quality system insures that each valve Sure Seal supplies exceeds your application expectations.
Non-wetted, 360 deg. radially-loaded, elastometric energizer is engineered to provide uniform pressure to the outer circumference of the liner and disc, ensuring absolute bubble tight shut-off
Unique, spherically-shaped disc and liner eliminates the axial cold flow and deformation problems typical of conventional lined butterfly valves, resulting in a reliable, maintenance-free, environmentally safe stem seal
The disc swing is compatible with PTFE and other fluoropolymer-lined piping systems as well as other metallic, lined and non-metallic piping systems, resulting in the elimination of spacers during installation
ISO 5211 mounting flange allows the direct mounting of actuators, eliminating hysteresis and costly automation hardware
ProTef proprietary lining and molding technology features a minimum lining thickness of 3mm and was developed to provide long-term resistance to permeation, absorption, and swelling
ProTef technology features superior joint, creep and vacuum resistance, especially at elevated temperatures
LBF design features spherically-molded and machined, wide-liner sealing surfaces that are securely anchored within the faces of the valve body by a series of concentric serrations, resulting in the reduction of radial cold flow
Robust body construction is designed to be as strong as the PN10/16 counter flanges to which it will fastened - eliminating deflection problems and resulting in improved flange sealing properties
Polyester Polyeurathane powder coating for external corrosion protection
Ideally suited for chlorine gas service
