A rising-stem globe valve for throttling and isolation, with NPT threaded only ends, 1/2″–2″ (DN15–DN50), in SS316. Rated 800 PSI, built to API 602. Graphite packed — built to run part-open, unlike a gate valve.

Throttling duty, NPT threaded only ends, built to API 602.
A rising-stem globe valve in 1/2″–2″ (DN15–DN50), body in SS316, rated 800 PSI. In a globe valve the flow turns: up through a seat opening, past a disc that lifts squarely off that seat, and down again to leave. That geometry is what lets it be set and held anywhere between shut and fully open.
Four times the pressure of the 200 PSI version - but note the temperature: 200 C, not 425. And this is NPT only, with no BSPT option.
Running it part-open is normal service, not abuse. A gate valve held part-open erodes its own seat permanently; a globe valve is built for it.
At 2″ in cast steel a globe is 203 mm face-to-face against 178 mm for the gate. It will not fit the gap a gate valve came out of — measure the run.
Metal seating and a graphite-packed stem, rather than a PTFE seat. That is why globe valves regulate steam and hot oil where a ball valve stops at 150 °C.
As published. We print the catalogue figure rather than inferring one from a sibling variant.
Flow entering beneath the disc, unless the manufacturer says otherwise — it makes the valve easier to open against pressure and keeps the packing out of the throttling stream.
The end type is the first decision and cannot be changed later. Check it against the pipework, not the pressure rating — all ten variants compared.
All photographs of the stocked item, not renders.
A rising-stem globe valve with the handwheel fitted. The stem travels as the valve opens, though not as far as a gate valve’s — the disc does not have to clear the bore.
Note the shape: the flow turns twice inside it. That is what makes it controllable, and also why it is longer face-to-face than a gate valve of the same size.
Where the graphite packing sits. Installed flow-under-the-seat, the packing stays out of the throttling stream.

Millimetres. Face-to-face L is the gap the valve needs in the run; on a rising-stem globe valve you also need headroom above it, because the stem travels up as it opens.
| Size | DN | Face-to-face L | Handwheel W |
|---|---|---|---|
| 1/2″ | 15 | 80 | 100 |
| 3/4″ | 20 | 92 | 100 |
| 1″ | 25 | 110 | 122 |

| 2″ | 50 | 173 | 180 |
A globe valve is longer face-to-face than a gate valve of the same size — 203 mm against 178 mm at 2″ in cast steel. It will not fit the gap a gate valve came out of. The rising stem also needs clearance above.
Measure the gap in the run against it. On a replacement, measure the valve coming out rather than trusting a drawing — and remember a globe valve of the same size is longer.
Where a letter is ambiguous or mislabelled in the catalogue we say so rather than guess at what was meant.
A valve must not hang on the pipework, and must never be used to pull a misaligned joint together.
NPT threaded only — the end type is the first decision and cannot be changed after ordering.
Sixteen callouts, and sixteen items in the parts list below — the two match one for one. The dimension letters are the column headings in the size table above: DN nominal size, L face-to-face and W handwheel.
Callout numbers are the item numbers in the parts list below, and the dimension letters are the column headings in the size table above. Nothing on the drawing is named only there.
The drawing shows the disc lifting straight off its seat, with the flow turning twice through the body. That is what lets a globe valve be held part open — and why its pressure drop is higher than a gate valve's at full lift.
This is a catalogue section, not a manufacturing drawing: no tolerances and no material callouts. Order spares by the item numbers in the parts list.
The manufacturer’s item numbers, so a spares order matches the parts list.

They match the callouts on the sectional drawing, so a spares order matches the section rather than a description.
Everything else is a casting or a fastener. On an isolation valve those two surfaces take the duty every time it is closed.
It is also the part that beds in. A small re-tighten of the gland after the first heat cycle is normal.
A bent or scored stem is the usual reason a globe valve will not seat, and it is the part that moves furthest every cycle.
If you need to know what touches your fluid, the whole list is above — we have not summarised it.
Factory proof tests. Not working pressures — the shell test proves the body, the seal test proves the gate against its seat. Do not design to them.
| Item | Value |
|---|---|
| Nominal Pressure | 800 PSI |
| Strength Test Pressure | 21.5 MPa |
| Back Seat Test | 15.5 MPa |
| Sealing Test | 15.5 MPa |
| Air Sealing Test | 0.6 MPa |
| Max working temperature | 200 °C |
The shell test proves the body and the seal test proves the gate against its seat. They are proof tests well above the working rating, and the valve is not intended to operate there.
That is the number to design to, at 200 °C.
Every variant in this range is inspected and tested to it, so the figures on the other nine pages can be read against these directly.
Running part-open is normal service for a globe valve, not abuse — but the disc and seat still take the whole duty. On a valve that is adjusted often, those two faces are what to ask about.
EN 10204 3.1 is available on request and the castings carry heat numbers — ask with the order, not after the goods arrive.
End type first, then the standard, then the material.
All ten side by side: the comparison table.
Throttling and isolation. A rising-stem globe valve with NPT threaded only ends in 1/2″–2″ (DN15–DN50), body in SS316, rated 800 PSI, built to API 602. The flow turns past a seat, and the disc lifts squarely off that seat, so flow can be set and held anywhere between shut and fully open.
Yes — that is the point. Running a globe valve part-open is normal service, not abuse. A gate valve held part-open erodes its own seat permanently; a globe valve is built for it.
No. A globe valve is longer face-to-face at the same size — at 2″ in cast steel, 203 mm against 178 mm. You need about 25 mm more in the run. Measure before ordering.
Rated 200 °C, as published. The packing is graphite and the seating is metal, which is what allows the heat — a PTFE-seated ball valve stops at 150 °C.
Flow-under-the-seat unless the manufacturer says otherwise — flow entering beneath the disc. It makes the valve easier to open against pressure and keeps the packing out of the throttling stream.

1/2″–2″ (DN15–DN50). Part numbers, the bill of materials and the test pressures are all on this page, as printed in the catalogue.
Designed and manufactured to API 602. Note that nine of the ten variants are tested to API 598, but the JIS 10K cast iron is built to the JIS F7307 / F7400 marine standards instead, so its figures are not directly comparable with the rest of the range.
It is handwheel operated and multi-turn, not quarter turn. Operating torque, turn count and any ISO 5211 pad are not published for this range — settle the actuation arrangement with us rather than assuming a top plate.
No flow characteristic curve and no Cv — which bites hardest here, because this is the throttling valve and the relationship between stem position and flow cannot be read off the sheet. Also no disc type, no operating torque, no ISO 5211 pad and no fire-safe certificate. EN 10204 3.1 is available on request; the castings carry heat numbers.
