Series LBF Lined Butterfly Valves
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
