Lug Butterfly Valve with threaded body holes for dead-end service and easy maintenance access.
African Valve supplies lug butterfly valves in South Africa for flow isolation and regulation across water, wastewater, mining, chemical, power, oil and gas, and general industrial applications. The lug-style body incorporates individually tapped mounting holes, allowing the valve to be secured between pipeline flanges without relying on a continuous through-bolt arrangement.
Lug butterfly valves use a quarter-turn rotating disc to open, close or regulate flow. Depending on the design, they can be supplied with concentric resilient seating or offset disc arrangements, along with different body, disc, shaft and seat materials for specific service conditions.
