Gate Valves

About Gate Valves

Avail from us wide range of Gate Valve  which is widely recognized for its ability to efficiently regulate the flow of liquid. It is a mechanical system that contains a metallic disc which in off condition, is placed perpendicular to the flow and thereby perfectly blocks it. But when the adjuster is moved, the disc creates an opening to allow the flow to pass through the valve. Besides, Gate Valve is immune to corrosion or abrasion, and therefore, it has the sufficiently long service life.Gate Valves under our Make covering all types like bolted bonnet, Pressure Seal Bonnet, Seal welded Bonnet, Union Bonnet etc. USMANI VALVE Gate Valves in Solid Wedge, Flexible Wedge and Dual Disc Designs are made as per API-600 and API 6D. Pressure rating from 150# through 2500# in Forged and Cast Carbon Steel, Alloy Steel, Stainless Steel of all Grades and Super Alloy Steel like Alloy-20, Haste alloy-C, Duplex and Super Duplex Steels. USMANI VALVE Gate Valves are offered with smooth machined full bore and full opening of Wedge to make certain that there is an eradication of additional pressure drop across the Valve. Screwed-in or Seal Welded Seat Rings guarantee perfect tightness for a longer period of service. In high temperature and high  pressure Valves, Seat Rings are either integral with body or seal welded as per standard practice and process for highest perfection and safety.

Gate Valves are offered with precisely machined and lapped back seat to guarantee re-packing under pressure while the Valve is in full open condition. Availability of Solid Wedge, Flexible Wedge, Dual Disc Wedge and Parallel Wedge designs put forward maximum choice to clients for appropriate selection.

USMANI VALVE Gate Valves make sure about smooth operation, tight shut off, consistency, high safety and durability.
