Severe Service Ball Valves
The “S” Series, a “Second Generation” Severe Service ball valve line, is designed to bring the problem solving ability of Severe Service Metal Seated Ball Valves to the core markets of Ladish, which are products manufactured from Nickel Based alloys as well as Chrome and Exotic materials. The design and coating technology offered by Ladish for manual, automated on-off and highly cycled process valves picks up where more traditional technology leaves off.
Ladish’s fully automated lapping technology ensures each severe service ball valve provides reliable and consistent tight shut-off to all recognized industry standards and your process conditions. Installed in a wide array of “high energy” services, this valve proves to stand the test of time. When performing under extreme conditions such as high temperature and pressure, corrosive service or erosive conditions, the S1 and S2 series ball valves should be your go-to choice.
As important as tight shutoff is to system reliability, meeting the Low Emission requirements of our customers is the top priority. This 2020 design was done with modern low emission requirements as a basis, not an afterthought. Stem Stabilization, multiple seals, extended bonnet systems, and new high-temperature materials are just a few of the options available to meet the requirements imposed on modern industry.

S1 SERIES

Compact and Economical Design with Removable / Replaceable trim, Low Emissions, and available in a wide range of material and coating options. Well suited for Manual Valve applications and those with bore sizes greater than 8”.
S2 SERIES

This “Second Generation” Metal Seated Ball Valve design provides only one through leak path, while retaining the feature of fully Removable / Replaceable Seats, Stem and Ball. The “Captured Flange Seat” allows exact thermal matching of all trim material for improved resistance to high temperatures and rapid temperature change. Designed for the most demanding Automated applications and where tight shutoff on gases is required.
