Versatility &  Reliability

The Sesto Valves M15/M30F Series direct mount flanged floating ball valve design starts with a high quality investment cast body, designed and tested in compliance with ASME B16.34 standards.  Precision machined surfaces and tighter manufacturing tolerances allow for precise assembly and fitting of body components and seals.  Because of reduced dimensional variations, seats can be designed for minimal compression.  This results in lower, more consistent torques and longer seat life.  Every valve is factory tested and serialized for quality control and traceability.

Low Torque Design

Larger stem and seats with much less compression and precision machined sealing areas give us a consistent and reliable lower torque than our competitors.
