Overview and Application
The sleeve bellows control valve adopts sleeve guide and pressure balanced valve core, which has good sealing performance, large allowable pressure difference, good stability, compact structure, and bellows-sealed upper valve cover and bellows components. Make sure there is no media leakage. It is widely used in toxic, corrosive and other industries that require tight sealing in petroleum, chemical, metallurgy, pharmaceutical and electric power industries.
