Description

Trunnion Mounted Fully Welded Ball Valves
Jonloos fully welded, trunnion mounted ball valves are the best solution to avoid fugitive emissions from the valve body and stem seal in gas or underground applications. They are recommended for oil and gas applications, specially for gas transmission and storage. To comply with the specific requirements of such applications, all valves are bi-directional and include the double block and bleed feature. Therefore, venting and draining of the body cavity is possible in both open and closed positions.
