Big Size Cast Steel Body Trunnion Mounted Ball Valve Size 30 Inch Class 300
Product Description
The trunnion mounted ball valve has automatic pressure release function. When the temperature
of the medium in the valve increases and the abnormal pressure rises, the trunnion mounted ball valve can
automatically release the pressure without a safety valve, which is very important to ensure the safety of
industrial production.
