Description
Wedge gate Valves are for straight flow of fluid where minimum restriction is desired and are Bi- Direction valves. Gate Valves are intended to use widely in Steel Sectors, Oil and Gas, Power sectors, Refineries, Petrochemicals, Fertilizers ,Energies, and Water De-sanitation plants. These valves are suitable for Hydrogen and Oxygen services also. NACE requirement with carbon and carbon equivalent limitations and hardness values are best to use in Petroleum and Natural Gas industries- Materials for use in H2S-containing in environment in oil and gas production.
Gate Valve with non rising stem specially design for the water application. This Gate Valve are intended to use widely in water distribution, Water De-sanitation plant & Power sector.
