PRESREG Valves - Home

About us

All of the components that go into our products are manufactured on site, with the exception of springs and seals which are sourced from trusted UK and European suppliers, . Having in-house production facilities ensures we can offer the highest quality products and enables us to provide short leads times, and the capability to offer bespoke solutions if required.

All products are individually leak and pressure tested and certified prior to dispatch. We maintain full material source traceability for materials used and we are an ISO 9001:2015 accredited company.

Component machining on-site

PRESREG Valves has extensive experience supplying products for high pressure Oxygen and Hydrogen service and can offer specialist cleaning to BOC / Linde specification 5100080.

Our experience of working with Hydrogen led us to starting our sister company – H2 Technology.

Under the H2 Technology banner, we have developed a range of products aimed at servicing the rapidly growing 350 bar and 700 bar Hydrogen fuel market.

This includes our 703 series pressure regulator, which utilises an innovative and unique design to create a small, lightweight and reliable device that was the first of its kind in the UK to be granted EC79 type approval for use on road going vehicles!  This product has been awarded a UK patent. 

Additional products include a range of regulators, relief valves, filters and stop valves for both 350 bar and 700 bar systems.

We have a proven track record of working with customers to develop solutions for bespoke applications, ranging from custom high capacity regulators used on large industrial plant, down to bespoke equipment for personal mobility devices.

All H2 technology products are also listed on this website, but for more information on our Hydrogen specific products, please visit the H2 technology website on the link below:
