Industrial Ball Valves

Uncompromised Design

The industrial ball valve market abounds with a myriad of standard application valves.  As the industry moves forward, modern manufacturers have responded to price competition by reducing wall thickness and quality of raw materials – to the detriment of the product.

Sesto Valves midrange ball valves stand out from the competition with true B16.34 wall thickness, precision machining and high quality gaskets.  No corners were cut in design. Our valves are heavier because we use more material, even jumping to a 6-bolt design at lower diameters to ensure proper safety factors.
