Gas ball coupler-joined valves
are connected to pipeline by means of standard couplings. The thread is sealed by tape FUM or oakum impregnated by iron minium.
The parameters described in the table «Technical parameters» are indicated as follows:
- Valve type (GShK)
- DN
- Medium
- PN
- Climatic modification
