BZ41H jacket insulation gate valve

The thermal insulation gate valve is mainly used in various systems such as petroleum, chemical industry, metallurgy, and pharmaceuticals. The jacket of the valve is welded between the two flanges of the valve. The side and bottom of the valve are provided with the connection port of the jacket. Free flow of steam or other hot insulating media ensures smooth flow of viscous media through the valve.
