ANSI 150 SS316 globe valve, 1" to 4"

A rising‑stem globe valve for throttling and isolation, in 1" to 4" (DN25 to DN100), with ANSI 150# flange ends and a body in Stainless steel — A182 F316 forged, A351 CF8M cast. Rated 150 PSI, designed and manufactured to API 602 and BS 5352, inspected and tested to API 598.

Inside, flow turns up through a seat opening, past a disc that lifts squarely off the seat, and turns down again. The stem moves the disc towards or away from the seat, so the gap changes smoothly with stem position and a flow can be set and held. That is the job a gate valve cannot do — a gate parked part open vibrates and wears its seat. The cost is pressure drop even fully open, because the path turns twice. Globe against gate.

• The two bands are genuinely different valves. 1"–1½" is a forged F316 compact body with the seat machined into it; 2"–4" is a cast CF8M body with a separate disc, back seat and gland. Both are 316‑grade stainless and both are published in full below — order spares against the band your valve came from.
• The small band is rated to −20 °C, as published. It matters only on genuinely cold duty; if you are near it, ask us to confirm with the factory before ordering.
• Part numbers read VL‑S‑GL‑, which is correct. GL is this manufacturer’s globe valve code. The forged steel version’s codes are confirmed with the factory on enquiry.
• 425 °C on a stainless valve, because it seals metal to metal. There is no polymer seat here. A SS316 ball valve in the same material stops at 150 °C, and the reason is entirely its PTFE seat.
• The handwheel is A197 or A216 WCB, not stainless. Item 15 on the forged band and item 16 on the cast one. Dry, outside the pressure boundary, and paintable.

Three angles on the same valve. Photographs of the stocked item, not renders.

1" to 1½" (DN25 to DN40) — forged F316 — 15 parts

2" to 4" (DN50 to DN100) — cast CF8M — 18 parts

The manufacturer’s sectional drawings, one for each size band. Callout numbers correspond to the matching parts list.

• The item numbers are the manufacturer’s. They are the callout numbers from the sectional drawing, which is why a number can repeat a part name at a different position. We have left them exactly as published so a spares order matches the drawing.
• The seating surfaces are what wear. On a valve that runs part open, flow through the gap is fast, and the disc face and seat take that. They are the parts to ask about first.
• Everything here is published, not on request. If you need to know what touches your fluid, the whole list is above.

1" to 1½" (DN25 to DN40) — forged F316

2" to 4" (DN50 to DN100) — cast CF8M

• ⚠ Do not design to these figures. They are manufacturing proof tests well above the working rating — the shell test proves the body, the seal test proves the disc against its seat. The valve is not intended to operate there.
• Gas tightness is 0.6 MPa, the same figure across all ten variants in this range. It is the one number that does not move with class, size or material.
• The temperature ceiling is the material, not a seat insert. A globe valve seals metal to metal and packs the stem with graphite, which is why the steel variants here reach 425 °C where a PTFE‑seated ball valve stops at 150. All ten compared.
