Valves for dummies: understanding your Wellington Pipework Project (Part 1)

If you’re discussing pipework design for your up-and-coming Wellington industrial plumbing project, there’s a term that might come up more that once when mulling over plans: valves. 

Simply put, valves are devices that direct or regulate water flow at their opening and closing. Valves are possibly the most important aspect of your pipework system! Without valves, you would have no control over your industrial pipework system.Without further delay, here are a few valves you might hear of in your next pipework project:

Gate Valves

These are the most commonly used and talked about valves in the Wellington industrial pipework industry. Gate valves adopt their name from the concept of a normal opening and closing gate: they lift to allow the flow of fluid. Gate valves are able to fully open and fully close, and are useful in isolating pipe systems, or wherever a straight-line flow is located in your pipework plans.

These valves are typically controlled by hand-wheels or electric motors.

Globe Valves

If the regulation of liquid flow in your building’s pipeline is what you’re after, then Globe Valves are the valves for you. Rather than having the typical ‘all or nothing’ capacity of a gate valve, these valves regulate liquid with a movable disk and stationary ring seat mechanic, known as a plug. The handy feature of a globe valve is that it can be positioned at an angle rather than just on straight pipework lines.

These valves are tough and extremely effective in areas where thicker fluid is expected to flow, and they are tough with  almost no likelihood of corrosion occurring.

Needle Valves

Simply a variation of the globe valve, Needle valves are (as the name suggests) perfect for finer points of flow. If you need a more concentrated, controlled valve for the job, then needle valves are your valve of choice: their slender tapered plug in contrast to that of the Globe’s.


If you’re still new to the concept of drainage pipework plans, but you’ve got a large-scale plumbing system design to work with, then keep an eye on our blog for tips on pipework design lingo. There’s plenty to learn, but – when in doubt – don’t hesitate to talk to the team at PipeSpec! Keep an eye out for our part 2 of this blog next month!
