BOLTED BODY FLOATING BALL VALVES
High-performance valves engineered for the oil & gas, chemical, petrochemical, water, and energy industries
Negri Fratelli bolted body floating ball valves are designed to deliver maximum safety, reliability, and long-term ease of maintenance. The bolted body design provides direct access to internal components, simplifying inspections, scheduled maintenance, and seat or seal replacement without compromising the valve’s structural integrity.
Ideal for a wide range of applications, including industrial plants, gas and fluid distribution networks, pipelines and refineries, water treatment systems, and energy projects.
