Butt Weld Globe Valve

Our valves utilize cutting-edge technology, undergo rigorous quality control, ensuring outstanding performance and durability.

Butt Weld Globe Valve

SEDELON butt weld globe valves are BS 1873 shut-off and throttling valves engineered for precise flow control and bubble-tight isolation in high-pressure pipeline systems. Covering NPS 2″–12″ and pressure classes 150 through 1500, they are built from a full material range — WCB/WC6/WC9 carbon and alloy steel, CF8/CF8M stainless, LCB/LCC for cryogenic duty, and Monel, duplex and bronze for corrosive and offshore service. The butt weld ends (ANSI B16.25) are welded directly into the line for a completely leak-free, flangeless connection that needs no gaskets or bolt maintenance. Every valve is pressure-tested to API 598 and backed by SEDELON’s OEM/ODM capability, EN 10204 3.1 mill certificates and short lead times for EPC contractors and distributors.

What Is a Butt Weld Globe Valve

A globe valve uses a spherical body and a movable disc that seats against a stationary ring to start, stop or regulate flow. Compared with a gate valve, a globe valve sustains a higher pressure drop but delivers far better throttling accuracy and a tighter seal under frequent cycling — making it the standard choice for isolation points that also need flow regulation. The butt weld end version removes the flange joint entirely: the valve is site-welded into the pipeline, eliminating a common leak path and reducing weight and footprint in buried or offshore installations.

Key Features

BS 1873 design with API 598 pressure testing for reliable shutoff.
Butt weld ends to ANSI B16.25 — full-bore, leak-free pipeline weld with no flange joints to maintain.
Face-to-face dimensions to ANSI B16.10 for field interchangeability.
Wide pressure coverage: Class 150 / 300 / 600 / 900 / 1500.
Full material matrix: carbon (WCB), alloy (WC6/WC9), stainless (CF8/CF8M/CF3/CF3M), low-temperature (LCB/LCC), and corrosion-resistant (Monel, 20# Alloy, Duplex 4A/5A, Bronze C95800/C95500).
Renewable seat and stem with API trim options (No. 01–57) for erosive and corrosive service.
Optional gear, pneumatic or electric actuation on request.

Material & Trim Selection

For high-temperature steam and refinery duty, choose WC6/WC9 alloy steel with STELLITE-faced trim (API Trim 05/08). For cryogenic and LNG service, LCB/LCC with extended bonnet and 304L/316L trim prevent embrittlement. For seawater, desalination and offshore platforms, CF8M, Monel, duplex (4A/5A) or aluminum bronze (C95800/C95500) resist chloride corrosion. Corrosive chemical lines can be supplied with Hastelloy trim and PTFE/RPTFE/PEEK seats on request.

Applications

Upstream and midstream oil & gas, pipeline stations and metering skids.
Refineries and petrochemical plants.
Power generation, including cryogenic LNG with LCB/LCC bodies.
Desalination, seawater service and offshore platforms (bronze / duplex / Monel).
Chemical and high-purity process lines (CF8M, Hastelloy).

Frequently Asked Questions

What is a butt weld globe valve used for?

It is used where a pipeline needs both reliable isolation and accurate flow throttling — such as bypass, sampling and control lines in oil & gas, refining and power plants. The welded end makes it ideal for buried or offshore lines where flange joints are undesirable.

Butt weld vs flanged globe valve — which should I choose?

Choose butt weld when the line is permanent, space- and weight-critical, or in buried/offshore service where a leak path must be eliminated. Choose flanged (ANSI B16.5) when frequent disassembly for maintenance or retrofit is required.

Which standards does the SEDELON butt weld globe valve meet?

Design and manufacture to BS 1873, face-to-face to ANSI B16.10, butt weld end to ANSI B16.25, and pressure testing to API 598.

What materials are available for high/low-temperature and corrosive service?

High temperature: WC6/WC9. Low temperature / cryogenic: LCB/LCC. Corrosive / seawater: CF8M, Hastelloy, Monel, duplex (4A/5A) and bronze (C95800/C95500).

Can you supply custom trim and actuation?

Yes. We offer API Trim No. 01–57 and gear, pneumatic or electric actuation, with engineering support for special ends and trim packages.

Globe vs gate valve for throttling — what is the difference?

A globe valve gives precise throttling and a tight seal under frequent cycling but a higher pressure drop. A gate valve is for straight on/off service with low pressure drop and is not suited to throttling.
