Product Description

 

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.
