Socket weld forged steel globe valve, ½" to 2"

A rising‑stem globe valve for throttling and isolation, in ½" to 2" (DN15 to DN50), with Socket weld ends and a body in Forged steel ASTM A105. Rated 800 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.

• ⚠ Welding it in is permanent, and it happens with the valve in the line. Follow the manufacturer’s procedure: valve part open so the disc is off its seat, heat kept off the gland, and graphite packing protected. A seat distorted by weld heat cannot be repaired in place.
• This is a socket weld valve — the dimension table publishes socket bore D and socket depth L1. For threads, use the NPT version of the same forging.
• Tested slightly lower than the threaded valve at the same rating. 19.5 / 14.3 MPa here against 21.0 / 15.4 on the threaded version, both at 800 PSI. Both are far above the working pressure; we publish each as printed.
• Identical 16‑item parts list to the threaded valve. Same forging, same trim, same graphite and B7 bolting. Spares interchange; the end connection does not.
• The ½" socket is shallower than the rest. L1 = 9.6 mm at ½" against 12.7 mm at every other size. Set the pipe insertion depth from the table, not from the last joint you did.

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

The manufacturer’s sectional drawing. The callout numbers correspond to the item numbers in the 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.

• ⚠ 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.
