Five principles
How quality is built in.
01
One standard, every market
Whether a valve ships to Europe, the Americas or Asia, it is built to a single uncompromising specification — no lesser grades, no shortcuts.
02
Independently proven
Compliance is confirmed by accredited third-party laboratories and audits, not by our word alone — so buyers can specify with confidence.
03
Consistent, unit to unit
Tight process control means the millionth valve performs exactly like the first, giving cylinder fillers a predictable, reliable fit.
04
Traceable for life
Every valve can be traced back to its material batch and inspection record years later — accountability that lasts as long as the product.
05
Safety, always verified
Nothing is taken on trust. Each stage is signed off before the next begins, because the valve is the most safety-critical part of a cylinder.
How we make them — from raw brass to finished valve
Six manufacturing stages. Nine critical quality checks.
01 Material verification
02 Precision forging
03 Machining
04 Automated assembly
05 PLC-driven testing
06 Global dispatch
01
Material verification
Every batch of brass is checked on an in-house spectrometer for precise chemical composition.

Stage 01 / 06
One valve's journey
Every valve. Every check.
Follow a single valve from raw brass to dispatch. It doesn't move on until it passes.
01
Raw brass
Every supplier batch verified on our in-house spectrometer to EN 12164/65.
02
Forging
Hot-forged bodies inspected for form and finish.
03
Machining
Threads checked on an in-house contour machine.
04
Outlet imaging
Critical outlet connections imaged and recorded.
05
Seals
Rubber tested for n-pentane, ozone and hardness to EN 549.
06
Assembly
Assembled on automated lines for consistent quality.
07
Pressure relief
Where fitted, set and discharge tested on automatic machines to the applicable specification, including EN 13953, with results recorded.
08
Leak test
Leak-tested on PLC-controlled benches, with results recorded.
09
Packaging
Packed and labelled for export, traceable to its production batch.
Certifications & approvals — approved where it matters
Sustainability
Brass that lasts. Energy that counts.
Quality and responsibility run through the same system. Our plant is certified for environmental and energy management, and every valve is made from brass that stays in the recycling loop.
Read our sustainability commitments →01
ISO 14001:2015
Environmental management system covering the whole Sankrail plant.
02
ISO 50001:2018
Energy management — measured, reviewed and reduced year on year.
03
Recyclable brass
Turnings and offcuts are collected and remelted; brass valves are fully recyclable at end of life.
04
Built to last
Long-service valves mean fewer replacements and less waste across the cylinder fleet.
