Globe valves for steam, fuel and process regulation
Stable throttling for steam, fuel and process lines. Cast and forged, ½" to 24".
Overview
A globe valve moves a plug onto a seat in the centre of the body, which gives fine, repeatable control of flow. It is the standard choice wherever a line has to be throttled by hand: steam headers, fuel oil, boiler blowdown, cooling-water balancing and sampling points.
We supply cast steel globe valves to BS 1873 and ASME B16.34, and forged steel globe valves to API 602, with bolted bonnets, outside screw and yoke, and plug or needle discs. Bellows-sealed globe valves are available for fugitive-emission service, and pressure-seal designs for Class 900 and above.
Our stock covers the materials Pakistani power plants and refineries specify most often: WCB for general service, WC6 and WC9 for high-temperature steam, CF8M for corrosive duty, and A105, F11, F22 and F316 for forged valves.

Specifying the right globe valve
A globe valve is the right choice when the valve must set a flow rate, not just stop it: steam and condensate stations, cooling-water balancing, fuel and chemical dosing lines, sampling and drain lines that are cracked open for minutes at a time. The disc closes onto a seat in the body, so the position of the stem sets the opening precisely and the valve tolerates throttling without damage. The cost is pressure drop: a T-pattern globe valve loses several times more head than a gate valve of the same size when fully open. Where that matters, specify a Y-pattern body, which keeps most of the control with far less loss.
Cast bodies above 2" follow BS 1873; 2" and below are forged to API 602. Pick the disc for the duty: a plug disc for general regulation, a needle or V-port disc for fine control at low flows, a parabolic disc for erosive service. Install flow-under-disc (to open) unless the line is steam over 600 °F, where flow-over-disc keeps the stem cool. Bellows-sealed stems satisfy fugitive-emission limits on hydrocarbon and toxic service, and chrome-moly bodies (A217 WC6, WC9) with hard-faced trim are standard on main steam and feedwater.

Why tenders get rejected, and how we avoid it
Globe valve tenders in Pakistan are often evaluated on trim hardness and stem sealing as much as on price: a quote without the trim designation, packing material or the manufacturer's hydrostatic report is marked non-responsive. We quote with the full data sheet, the manufacturer's API or BS conformity certificate and an authorisation letter, so your submission passes technical scrutiny the first time. More on API licences, authorisation letters and certificates.

Frequently asked questions
Which direction should flow enter a globe valve?
Normally under the disc (flow-to-open), which is marked by an arrow on the body. For some high-temperature steam duties the manufacturer specifies flow over the disc; we confirm this on the datasheet.
Why is the pressure drop higher than a gate valve?
The flow path turns twice inside a globe valve body. That is what gives it good control, at the cost of a higher pressure loss. Where the valve will only ever be fully open, a gate valve is the better choice.
Can you supply bellows-sealed globe valves?
Yes, for fugitive-emission and toxic service, with the bellows tested to the relevant EN or API standard.
Globe valve vs ball valve for throttling?
A globe valve. A standard ball valve controls poorly below about 30 % open and its soft seats erode under throttling. V-notch ball valves exist for control duty, but for manual regulation a globe valve is cheaper and more predictable.
T-pattern or Y-pattern?
T-pattern is compact and standard for most regulating and shut-off duty. Y-pattern puts the seat at about 45 ° to the flow, cutting pressure drop by roughly half, and is specified on long steam lines and anywhere the pump has little head to spare.
