Batley Valve® BV 26000 Metalseal
The Batley Valve® Metalseal design lends itself for use on higher temperatures and abrasive services where a PTFE seal would not be acceptable. It’s used in applications where high operating temperatures or abrasive services preclude the use of elastomer or polymeric seals, but a superior shutoff is still required. This design is an inherently fire-safe design and has a shutoff 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 disc minimizes wear and seating torque. Hard surface deposits such as hard chrome plating, Stellite and tungsten carbide are available.

- Valve is suitable for higher pressures and temperatures than PTFE allows.
- The vane’s streamlined design improves the flow line and reduces the head loss. ANSI Class IV leakage as standard. Special valves can be manufactured with bodies drilled to suit flanges up to ANSI Class 2,500 lb. The valve can be supplied with wafer, lugged and double-flanged bodies and incorporating full and reduced bore sizes to suit the application.
- Seat design enables stable tight shutoff performance, both in direct and reverse flow conditions. Alternative seal retainer available to suit spiral-wound gaskets. Sizes up to 1,200 mm on request. Buttweld body designs available on request.
