Versatility &  Reliability

The Sesto Valves M32 Series direct mount 3-pc 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.  The 3-pc swing-out design and array of seat options allow for flexibility to meet a range of operational requirements in one simple, reliable design.  Every valve is factory tested and serialized for quality control and traceability.

Why Sesto?

The Sesto Valves 3-pc design is compliant to ANSI Class 800 (2000 WOG) as per ASME B16.34 standards. In fact, the center body wall thickness is engineered with enough safety factor to exceed Class 900 rated pressures. Body gaskets are 50% thicker than industry standard to ensure better body sealing. Non-encapsulated seats with true swing-out body design allow for easy maintenance.

Premium investment cast body and end caps with chemical composition and hardness controlled to meet NACE standards. Sealing areas are machined within +/- 0.002” for precise assembly and less dimensional variation, allowing for lower seat compression ratios. As a result, seats last longer and torques are lower and more consistent.

Several design features contribute to high reliability and long-life performance. Oversized stem and body wall thicknesses provide a factor of safety at higher pressures. Lower seat compression and reduced torques result in extended seat life. Precision machined sealing surfaces and thicker body seals are less likely to leak over time.

The Sesto Valves 3-pc design is ANSI B16.34/B16.5/B16.10 and NACE MR0175 compliant, API 607 Fire-Tested and Certified. Valve acceptance testing is performed per API 598 (ISO 5208 upon request) and stem packing tested to ISO 15848 per customer requirements. Pressure Equipment Directive (PED) certification is available for the European market.
