Product overview
Insulation gate valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other systems. The jacket of the valve is welded between the two flanges of the valve, the side and bottom of the valve are provided with a connecting port of the jacket, and the jacket can flow freely through steam or other heating insulation medium. Ensure that viscous media can flow smoothly through the valve.
Product features
The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium.
Opening and closing is labor-saving.
The flow direction of medium is not subject to eye control, disturbing flow and reducing pressure.
The utility model has the advantages of simple shape, short structural length, good manufacturability and wide applicability.
