Description

A triple offset wafer-type butterfly valve featuring metal-to-metal sealing for zero leakage and reduced seat wear. The wafer body is designed for installation between pipeline flanges in space-constrained applications. Suitable for high-temperature and high-pressure service in oil and gas, chemical processing, and energy industries.
