PurityPlus® High-Purity Specialty Gas Regulators: Choosing the Best of the Best for Your Application

If you’re new to purchasing PurityPlus® specialty gases – or purchasing a gas from PurityPlus® that you haven’t used before – you’ll want to make sure you’ve got the right regulator for the application at hand. Of course, whatever the application, you can’t go wrong with PurityPlus® regulators. They’re designed to extremely precise standards of pressure control, which is absolutely essential to the safety and effectiveness of your work. Not sure which regulator is right for you – or how to go about finding it? Your Local PurityPlus® Partner will be happy to help. Any customer, though, regardless of experience, will find it easier to determine the regulator they need by following the tips provided and browsing the relevant product pages in the PurityPlus® Specialty Gases & Equipment Catalog. Take a look at it before you contact your local partner, at least to get an idea of what options are available to you.

While the catalog provides complete information on every PurityPlus® regulator available, a brief overview of the line might be helpful to get you started:

  • Is the gas or liquid you’re using corrosive or non-corrosive? PurityPlus® has regulators designed for safe use with one or the other. Its brass regulators, of either forged-body or barstock construction, are compatible with most non-reactive gases. If you’re using a highly corrosive gas in its anhydrous form, you’ll want one of the PurityPlus® regulators made of extremely corrosion-resistant 316L stainless steel. As a lightweight, economical alternative to stainless steel when only mildly corrosive gases are used, PurityPlus® also offers regulators made of aluminum.
  • A wide selection of single-stage regulators and dual-stage regulators is offered as well. Single-stage regulators, which reduce cylinder pressure in one step to deliver pressure within a specific range, are best used in applications where a constant delivery pressure isn’t critical. Applications that do require a constant delivery pressure are best served by dual-stage regulators, which maintain constant outlet pressure over the life of the cylinder.
  • PurityPlus® provides specially designed regulators, too – with its 400 and 455 series, in particular – for those rare occasions when a standard single- or dual-stage regulator isn’t sufficient. Those primarily would be applications requiring the use of unusually corrosive gases or extremely high pressures.
  • You’ll also find cylinder connections in the PurityPlus® catalog that conform to all worldwide standards. Good thing, too, because …
PurityPlus® specialty gas regulators find universal acceptance in laser gas systems, gas chromatography, aerospace operations, welding, high-performance purification systems, water-pressure reduction, engineering and gas management, and onsite gas generation, just to name a few applications. You can be sure PurityPlus® will have the regulator you need. Just follow the clear, step-by-step selection and ordering process shown in the catalog. And, as we mentioned earlier, if you still need help, you can always count on your Local PurityPlus® Partner to provide it.
