Purple Valves

Engineer-led support

Getting the valve wrong is expensive. Wrong material for the media and it corrodes out inside a year. Wrong pressure class and it never passes inspection. Wrong actuator torque and it won't shut against line pressure.
Purple Valves was founded by an engineer, and we've kept it that way. When you call us with a technical question, you get someone who can read your P&ID and your spec - not a call centre reading off a stock list.

What we can help with

Valve selection and sizing

Tell us the duty - media, pressure, temperature, line size, end connection, how often it cycles - and we'll tell you which valve type suits it and which ones won't. If a cheaper option will do the job, we'll say so.

Material and standards advice

Choosing between carbon steel, stainless, ductile iron or bronze for a given service, and making sure what you install meets the standard you're being held to - API, AWWA, ASME, NACE, WaterMark, UL/FM. If your spec calls for it, we'll confirm before you order, not after.

Actuation and automation

Torque calculations and actuator sizing for pneumatic and electric operation, including accessories and control packages. Sized properly, so the valve actually closes against the pressure it will see in service.

Documentation and certification

Datasheets, material and mill certificates, test reports and compliance documentation. If your project handover needs a paper trail, tell us early and we'll build the pack alongside the order.

Spares and cross-referencing

Got a valve in the plant with a worn seat and no supplier? Send us the tag, the nameplate or a photo. We'll identify the spares, or cross-reference it to an equivalent we can supply from stock.

Troubleshooting

Valve leaking, seizing or wearing out faster than it should? Walk us through it. Often the problem isn't the valve - it's the wrong valve for the duty, and the fix is a change in type or material, not another replacement.

Project and package support

Valve schedules, take-offs, tagging and staged delivery against your program. For project work we'd rather be involved at the schedule stage than quoting line items in isolation.

Industries we supply

Built for demanding environments

Before you get in touch

The more you can tell us up front, the faster we can give you a straight answer. Useful to have on hand:

  • Media, operating pressure and temperature
  • Line size and end connection type
  • Applicable standard or project specification
  • Whether the valve is isolating, controlling or non-return
  • Manual or actuated - and if actuated, the available supply
  • Any nameplate details or photos, if you're replacing an existing valve

Don't have all of it? Call anyway. Half the job is working out what's actually needed.
