Three-way heat insulated plug valve is widely utilized in petroleum, gas, electricity, etc. Plug is used as close member of plug valve. Rotating plug valve can open or close valve. Three-way heat insulated plug valve is used to connect or cut off medium in pipelines.
Advantages:
1. Having low fluid resistance.
2. Compact structure, low volume, light weight.
3. Good sealing
4. Without limitation of flow direction.
5. Without vibration.
