Working principle of insulation plug valve:

Insulated plug valves are used in various systems such as petroleum, chemical, metallurgical, and pharmaceutical industries to transport high viscosity media that solidify at room temperature. The clamp sleeve of the plug valve is welded between the two flanges of the valve, and the side and bottom of the valve are equipped with clamp connection ports. Due to the addition of a jacket, the connecting flange size of this type of asphalt insulation plug valve is one to two specifications larger than that of a regular ball valve of the same specification, but the structural length is the same as that of a valve of the same specification. There are two types of end face connections: flange and clamp. Steam or other hot insulation media can freely flow through the jacket, ensuring that viscous media can flow smoothly through the valve.

Scope of application of insulation plug valve:

Insulated plug valves are suitable for frequent operation, with fast opening and closing, lightweight, simple structure, relatively small volume, light weight, easy maintenance, and are not limited by installation direction. The flow direction of the medium can be arbitrary, with good insulation and cooling characteristics, while effectively reducing heat loss of the medium in the pipeline.
