Gate Valve

Dinesh Tube India manufacture all types of Gate Valves.  Gate Valves both Solid Wedge and Flexible Wedge Designs conform to API-600. Pressure rating from 150# through 2500# in Cast Carbon Steel, Cast Alloy Steel, Stainless Steel of all Grades and Super Alloy Steel like Alloy-20, CD4MCu., Hastelloy Valves are in regular production. we Gate Valves are provided with smooth machined full bore and full opening of Wedge to ensure elimination of additional pressure drop across the Valve. Long Screwed-in Seat Rings ensure perfect tightness for a longer period of service and replaceable after a long period of service. In certain cases of high temperature and pressure Valves, Seat Rings are either integral with body or seal welded as per recognized practice and procedure for maximum perfection and safety.

Our Gate Valves are provided with properly machined and lapped backseat to ensure re-packing under pressure while fully open. Availability of Solid Wedge, Flexible Wedge, Split Wedge and Parallel Wedge designs offer maximum option to clients for suitable selection.

Gaskets and Gland packing material are selected to suit service conditions like temperature, corrosion, erosion, pressure, vacuum and other applications. Our  Gate Valves ensure smooth operation, tight shutoff, reliability, maximum safety and longer life.
