Two-way cast steel plug valve is widely used for pipelines to connect or cut off medium in petroleum, gas, electricity, chemical industry, etc. Plug valve uses plus as its close member. Rotating plug can open or close valve.
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.
