Insulation jacket gate valve is mainly used in petroleum, chemical industry, metallurgy, pharmaceutical and other systems. The valve jacket is welded between the two flanges of the valve, and the side and bottom of the valve are equipped with the connecting mouth of the jacket. The jacket can flow through steam or other hot thermal insulation media freely to ensure that the viscous medium can flow through the valve smoothly.
