Forged Steel Gate valve
A gate valve is a control valve that either allows media to flow through unobstructed or stops the fluid flow. The main advantage of a gate valve is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve.
Gate Valves are used in large numbers throughout the hydrocarbon, energy, and process industries.
All our valve production activities meet the standards set by national and international agencies. Our valve products comparatively have longer functional life and performance consistency.
We offer following ranges of Gate valves for different industrial applications.
