Built to API 6D, with ANSI 300# flanges.
A quarter-turn ball valve that bolts into the line through ANSI 300# flanges, in 1/2″ to 6″ (DN15 to DN150). The body is stainless steel SS316 and it is designed and manufactured to API 6D, with face-to-face dimensions to ASME B16.10 and flange ends to ANSI B16.5.
On a flanged valve the standard is not paperwork — it is the dimensions. The ANSI 300# drilling has to match the flange it bolts to, and the face-to-face length has to match the gap in the pipe run. Both are in the size table. The other three flange standards we stock will not bolt to this one. All six compared.
Body, ball and stem in SS316 (with CF8M, the cast equivalent, where the part is cast). Everything wetted is SS316 or PTFE.
Seat, gasket, O-ring and packing are all PTFE — which is what sets the 150 °C ceiling, not the stainless.
The two cast-steel variants fit an SS304 anti-static device; this parts list does not include one. If you are on hydrocarbon duty and need the ball bonded to the body, tell us and we will confirm with the factory.
Studs, nuts and screws in SS304 — more corrosion-resistant than the A193 B7 bolting on cast steel, and lower strength.
DN15 to DN150. Unlike the Class 150 range, there is no 5″ here — it steps from 4″ to 6″.
Shell, seat and gas tightness, for service at −29 °C to 150 °C. Those are factory proof tests, not working pressures — do not design to them.
All photographs of the stocked item, not renders.
All stainless. Body, ball and stem in SS316 — there is no carbon steel anywhere in the pressure boundary, which is the whole reason to choose this over the cast steel version.
Raised face and bolt holes. This is the face that has to match your pipework — bolt circle D1 and hole pattern N-M in the size table.
Bolted bonnet. The stem runs up through the bonnet with PTFE packing around it — items 11 and 12 on the parts list.

Eleven sizes, dimensions in millimetres. The two figures that decide whether the valve fits are face-to-face L — the gap it needs in the pipe run — and the bolt circle D1 with its hole pattern, which has to match the mating flange. Letters follow the manufacturer's drawing; where a letter is ambiguous we have left it as published rather than guess at it.

Raised face height F is 2 mm to 1¼″ and 3 mm from 1½″ up, as printed.
It is the one dimension that cannot be worked around. ANSI 300# will not bolt to any of the other three standards we stock, whatever the pressure rating says.
Especially on a replacement — and measure the valve coming out rather than trusting a drawing.
It needs a clear 90° sweep and on the larger sizes it is long. Send us the space you have if it is tight.
A Class 300 body is far heavier than Class 150 at the same size — 43 kg at 4″ — and a flanged valve must not hang on the pipework.
Only 3″ (31.00 kg) and 4″ (43.00 kg) carry a figure in the source. We have left the rest blank rather than estimate — ask us and we will weigh one.
600 mm at 6″ and 500 mm at 3″ and 4″. Check the swing clearance before ordering — considerably longer than the Class 150 lever at the same size.

That is why this valve tops out at −29 °C to 150 °C whatever the body is made of.

Factory proof tests. Not working pressures.

They are manufacturing proof tests well above the working rating — the shell test proves the casting, the seat test proves the seal, and the gas test proves it holds low-pressure gas. The valve is not intended to operate there.
The one figure that does not change with class or material.
Stainless steel SS316 would take far more; the seat is what stops it. All six variants compared.
Flange standard first, then material.
All six, side by side: the comparison table.
Dimensions and part numbers are in the catalogue, as printed; stock and price are not — send the list and we confirm both.
No. An ANSI 300# flange will not mate with JIS 10K or PN10/16, even though the nominal pressures are close. The bolt circle, hole count and hole diameter all differ. Check the existing flange before ordering.
Body, ball and stem in SS316 (with CF8M, the cast equivalent, where the part is cast). Seat, gasket, O-ring and packing are all PTFE. Fasteners are SS304. Everything wetted is SS316 or PTFE.
Not listed on this variant. The two cast-steel variants fit an SS304 anti-static device; this parts list does not include one. If you are on hydrocarbon duty and need the ball bonded to the body, tell us and we will confirm with the factory.
API 6D is the pipeline valve standard — a heavier, pipeline-oriented specification than API 608, which the two cast-steel variants are built to. This variant is the only one in the flange end range built to API 6D, so it is the one to quote on pipeline work. Its flange ends are to ANSI B16.5 and face-to-face to ASME B16.10.
Shell 6.0 MPa, seat 4.4 MPa, gas tightness 0.6 MPa. Those are factory proof tests, not working pressures — well above the working rating, and the valve is not intended to operate there.
Because the limit is the PTFE seat, not the body. SS316 would take far more; the seat is what stops it. That applies to all six flange end variants whatever the body is made of.
They are the manufacturer's numbers — the callout numbers from the sectional drawing, not a tidied 1 to 14 list. We have left them exactly as published so a spares order matches the drawing.
1/2″ to 6″ (DN15 to DN150) — ten sizes; the Class 300 range has no 5″. The dimension table carries full dimensions and weights for every size.
