Gate valves are heavy duty, outside screw & yoke type, bolted bonnet, Flexible wedge/ solid wedge, Threaded or welded seat ring, rising stem with non rising hand wheel.

VSN Valves have a wide range of GATE VALVES in variety of types, sizes, pressure ratings and materials, with wafer type, screwed, welded or flanged connections. Flowjet Manufacture Gate valves in every size.

Ranging from the smallest to the largest size Gate Valve name is derived from the operation of the Gate valve. The Valve Acts like a Gate to stop or allow the flow through the valve. The valve can be opened by lifting the wedge out of the path of the flow Gate valves are actually designed for closing & opening full , so they are not suitable for the Throttling purpose. When the Gate valve is fully open, there is no Obstruction in the Flow path, resulting in very low pressure drop, & they are often suitable for the Hot Tapping & Pigging. 

Gate Valves are actually designed for use with the flow of liquids and Gases but there are variation to cope with the specific requirements.
