Butterfly Valves

AGB Triple-Offset Butterfly Valves deliver metal-seated, bi-directional, zero-leakage isolation in a compact, lightweight package. The triple-offset geometry eliminates friction between disc and seat during operation, dramatically extending service life. Available in wafer, lug, and flanged end configurations, fire-safe certified to API 607.

✓ Triple offset geometry — zero friction during operation
✓ Bi-directional metal-to-metal sealing
✓ Fire-safe certified to API 607 / API 6FA
