Sesto Block & Bleed | Forged

PRODUCT DESCRIPTION

Sesto's Block & Bleed ball valves represent premium Italian engineering and manufacturing excellence, designed specifically for critical service applications in chemical, petrochemical, and energy industries. These valves integrate two independent ball valves into a single body, achieving double block and double isolation while minimizing leak paths and reducing footprint.

With over 30 years of engineering experience, these valves are 100% designed, manufactured, and tested in Italy, ensuring complete control of product quality and material traceability. The forged body construction eliminates leakage risks from poor castings, while precision finish machining maintains tight tolerances for secure assembly in high-pressure, critical applications.
