Ball welding valves GShK

Gas ball welding valves

are connected to pipeline by means of welding. Advantages are full and reliable leak-proofness of connection, minimum service.

The parameters described in the table «Technical parameters» are indicated as follows:

1. Valve type (GShK)
2. DN
3. Welding method of connection to pipeline
4. Medium
5. PN
6. Climatic modification
