Description

The Batley Valve® Metalseal Butterfly Valve is used in applications where high operating temperatures or abrasive service preclude the use of elastomer or polymeric seals, but a superior shut-off is still required. This design is an inherently fire safe design and has a shut-off to ANSI/FC I-70-2 class IV. Double offset design and geometry of the valve and seal combine to ensure a uniform 360° seal contact in the closed position. The double eccentric action of the disk minimises wear and seating torque. Hard surface deposits such as hard Chrome plating, Stellite & Tungsten Carbide are available.
