Overview

Engineered for drilling-mud and slurry service, this API 6A mud gate valve delivers tight, full-bore isolation in the harsh, abrasive conditions of wellhead and mud-handling systems. The gate mechanism offers a clear, unobstructed flow path that minimises turbulence and wear, while hardened sealing surfaces resist the erosive action of solids-laden fluids. Manufactured to API Spec 6A, it gives operators reliable shut-off and long service life in high-pressure oil and gas drilling and production applications.
