Product Description

ANSI Trunnion Ball Valve, three piece trunnion mounted ball valve, size 56in, class 600lbs RF, 3pc bolted bonnet body design, body low carbon steel LCB and ball F304, stem 17-4Ph, seat DEVLON,gearbox operation.

ARAN manufacture Trunnion Ball Valves are available in an extensive range of designs, materials, sizes and pressure classes and are in full conformance with international production standards ANSI, ASME B16.34,API 6D, ISO17292,GOST, specifications etc. The API 6D standard ball valve is most prevail in all industry standards,for the API standard is the highest valve standard in all kind of industrial application. Even some times the valves end connection will be changed in DIN/GOST/GB, the valve design will follow the API standard as the higher quality level.

The valve according to valve size and pressure, engineer will decide the valve design the valve is 2pcs or 3pcs body . The body material forged or cast steel form will be determined by customer needs. For higher pressure class and big size the forged steel material will be better in NDE performance than cast material form. But the valve cost of the cast material maybe comparable cheaper than forged steel.
Forged steel material form valve has assured material good quality in body strengths and no internal defects, good surface looking, compared with cast material form, the valve castings process may has the risk for the body defects like internal scar or sand holes, the valve surface maybe not so good smooth, and the RT process of NDE must be applied for the body shell strength for the high pressure class 600LBS and above . NDE cost like RT is quite expensive and in case of failure will be time consuming, the valve forged steel material can pass the RT 100%, so the usual practice is just need do simple UT test of NDE.

The valves used in key critical pipeline, the forged steel material will be the first choice. ARAN sales engineer will consider customers valve application and valve cost select the most suitable valve for satisfaction.
