MARK Valves

Ball Valves are quarter-turn, straight through flow valves that have a round closure element with matching rounded seats that permit uniform sealing stress. Ball valves are used in situations where tight shut-off is required. The type of seat can vary with the valve pressure rating and materials of construction.

Ball Valves are available in a variety of body styles, including one-piece, two-piece, three-piece and flanged body construction. Each of these ball valves forms perfect specific advantages depending upon the requirements of the given application. Similarly they are designed using a wide variety of materials, as required by their application. Common Ball valve materials include brass, bronze, copper, cast iron, ductile iron, stainless and other steel types.

Ball valves are manufactured as per BS 5351 and tested in accordance to ASME B16.34. Face to face dimensions to meet ANSI B16.10, and flange dimensions to meet ANSI B 16.5.
