CAST STEEL GATE VALVES

D Valve in-house designed, manufactured and tested cast steel gate valves are complying international design standards such as API 600, ASME B 16.34, MSS SP-144 . The quality is ensured from the receipt of components till the dispatch of the valve to customer. We understand the pain of customers on maintenance of components/valves; these valves are designed and assembled with few components hence less maintenance required in service life. We assure our product range meets most of the customer requirement w.r.t size, pressure class, material of construction, design.
