Product Details

Working Pinciple.

Jacket butterfly valve is developed from triple eccentric metal seated butterfly valve,the only difference is jackets on the both side of valve body are welded on the outer body,steam or other overheating air can flow through jacket to prevent medium freezing under normal temperature,the nominal diameter of jacket butterfly valve is larger than ordinary tripple eccentric butterfly valve for same size,the max allowable pressure for steam and cold water is 1 MPa.
