Gate valve, BB, CS
Design
Datian cast steel gate valves are designed and manufactured to provide maximum service life and dependability. All gate valves are full ported and meet the designrequirements of American Petroleum Institute standard AP1600&API 6D. British standard BS1414 & BS EN 1984 and generally, conform to American Society of Mechanical Engineers standard ASME B16. 34. Valves are available in a completerange of body / bonnet materials and trims
Rang of Materials
Standard body/bonnet materials include nine grades of carbon, low alloyandstanlesssteel, for special applications they can be supplied in other grades of alloy andstainless steel. There's a full range of trim materials to match any service optionalpacking and gasket materials are available for a full range of service conditions
