PRECISION ENGINEERED VALVES

WHY WE BUILD THINGS THE WAY WE DO

With in-house design, tool-making and manufacturing we can ensure start to finish quality and consistency in our manufacturing processes, build quality and product specifications which are routinely inspected and verified by third party agents Lloyd’s Register Quality Assurance Ltd to achieve the essential ISO 9001 manufacturing standard. Our cylinder valves are manufactured entirely in-house, retaining that family-business ethos - pride in what we do and quality control over the whole process. 

  • The smoothest operation possible in a cylinder valve.
  • Appropriate production tolerances and unique design features.
  • Superb O-ring retention - eliminating “O-ring blow-out”.
  • Directionally ridged operating knob offering superb grip when opening the valve but a deliberately less effective grip on closing, reducing over-tightening and therefore excessive wear of the valve seat - a feature essential for Oxygen & high Oxygen % Nitrox cylinders.
