JIS 10K cast iron globe valve, 2" to 6"

A rising‑stem globe valve for throttling and isolation, in 2" to 6" (DN50 to DN150), with JIS 10K flange ends and a body in Cast iron — FC on the small band, ASTM A126 B on the large. Rated 10 kg/cm² (10K), designed and manufactured to JIS F7307, inspected and tested to JIS F7400.

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 test table prints a hydraulic body test of 2.06 MPa, with seal figures of 3.0 MPa on the small band and 1.57 MPa on the large band, quoted as the catalogue has them. These are factory proof tests, not working pressures; we confirm the applicable figure on enquiry.
• ⚠ At 5" and 6", confirm the dimensions with us before you cut pipe. That band publishes face‑to‑face 330 and 355 mm, flange thickness 23.9 and 25.4 and a 2 mm raised face, where the 2"–4" band uses metric thicknesses of 21 to 25 mm with no raised face — quoted as printed, and we check the size you need against a stocked unit.
• Rated 230 °C, as published — the figure that governs this valve. The ANSI cast iron version is rated 429 °C; choose by the published figure for the valve you are buying. All ten compared.
• ⚠ Cast iron is brittle. Support the valve independently, do not use it to pull a misaligned flange together, and do not strike it. On anything that vibrates or gets knocked, use cast steel.
• Tested to JIS F7400, not API 598. The other nine variants in this range are inspected and tested to API 598. If your specification names API 598 explicitly, this valve does not meet it on paper even though the test pressures are comparable. The standards by variant.

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.

5" and 6" (DN125 to DN150)

• ⚠ 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.
