Flanged ball valves GShK

Flanged connection to pipeline make it possible to assemble and dismantle repeatedly valves GShK

, to tighten firmly joints. Valves with adjusting flanges provide the valve installation in any position and do not require the angular alignment of flanged mounting holes.

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

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