Steel Wedge Gate Valves With Nonrising Stem
Destination:

The wedge gate valves are used for a complete or partial shutting-off of a fluid flow as well as for resuming the initial flow of the same fluid, for nominal pressures of 140, 210, 350 bar (2000, 3000, 5000 PSI) .
Working medium: water, gases, petroleum products and other similar fluids with a light corrosive action.
