Design notes
- Simple construction, easy to make and maintain
- The disc lifts straight off the seat with no sliding between the sealing faces: little wear, tight sealing, long service life
- Short disc travel, so the valve is lower than a gate valve, with a longer face-to-face length
- Media flows one way only, in the direction of the arrow on the body
- Higher flow resistance and operating torque than a gate valve; for full-bore on/off service choose a gate valve

FAQ
Frequently Asked Questions
Globe valve or gate valve: which do I need?
Choose a globe valve when you need to throttle the flow or operate the valve often, and when tight shut-off matters. Choose a gate valve for lines that run fully open or fully closed with a low pressure drop, such as our GB/T 12234 gate valve.
Which way round is a globe valve installed?
Follow the arrow on the body: the media flows one way only and must not be reversed. Leave room above the handwheel to lift the stem.
Can a globe valve be used to throttle flow?
Yes. The disc moves straight onto the seat, so the opening changes smoothly with the handwheel. That is why globe valves are used where the flow has to be regulated.
Which body material should I choose: WCB, CF8 or CF3M?
WCB carbon steel for non-corrosive water, oil, gas and steam. CF8 (cast 304) for general corrosion resistance. CF3M (cast 316L) for chlorides, seawater and chemical media.
Are your globe valves API certified?
They are designed and built to API 623 and pressure-tested per API 598. We do not hold an API Monogram licence.
What documents ship with the valve?
A product test report with the heat number of the body casting, chemical composition, mechanical properties and the pressure test results. We welcome third-party inspection (e.g. SGS or BV), arranged and paid for by the buyer.
What is the lead time?
Standard sizes ship in 15–20 days. Large sizes and special options may take longer; we confirm the delivery date with your quote.
