Metaval’s Triple Offset Butterfly Valve is engineered for high-integrity sealing in critical service applications involving high pressure, temperature, or corrosive media. The offset design eliminates friction between the disc and seat during operation, ensuring zero leakage and long-term durability. This valve is ideally suited for shut-off applications where safety, performance, and longevity are non-negotiable.
