Versatility &  Reliability

The Sesto design allows for the use of all types and materials of construction and may be installed in any flow configuration and orientation.  Our customizable spring configurations and guided seat design gives the option for a carbon steel body and end enclosures with a duplex or stainless seat module.  We have many different metal seated options for a variety of high temperature, corrosive, or abrasive applications.  Our experienced team of engineers can design and build the right valve for your exact requirements. Our precision machined innovative design has been tested to the highest standards and may be used in virtually any application with confidence.  Reliable repeat performance is our responsibility to you.

Fire-Safe &
Fugitive Emissions Certified

Packing arrangement is Fire-Safe for critical applications and Fugitive Emissions ISO 15848 certified.

End Connections

Why Sesto?
True Cryogenic Design.

Forged 316 Body
The forged body eliminates the possibility of any leaks due to casting defects.

1-PC Extended Stem
Our stem is made of one solid piece extended to the valve body. The packing is insulated and there is no leak path in the extension. Our proprietary extension seal design helps maintain flow temperatures giving the end user energy savings.

PCTFE (KEL-F®) Seats lapped to the ball as standard
Our seats are lapped to the ball giving us very tight tolerance and shut-off while lowering our torques dramatically. Our seats do not leak.

Fully Tested Valves to -196°C (-320F)
We test our valves per industry standards and perform tests to Cryogenic Temperatures -196°C (-320°F) and then test again at ambient temperature with water.
