Specialty Gas Valve

What Makes Our Specialty Gas Cylinders so… Special?  The cherry on top of our specialty gas cylinder is a packless diaphragm valve.  The four general valve types are the packed valve, the O-ring valve, the pressure seal valve, and the diaphragm valve. Most cylinders require at least one of them in order to fill or empty the gas inside. Each valve type has advantages and disadvantages, based on the application.  We outfit our specialty gas cylinders with the diaphragm gland seal design pictured because this valve prevents gas contamination, offers high resistance to leakage, and features a robust construction for safe operation and reduced maintenance. This premium valve has no threads or lubricants in the gas stream to generate particles or contaminate the gas.  By using metal diaphragms instead of Teflon packing, this design achieves superior leak integrity at the top works of the valve and stem. Many shipping regulations require this type of cylinder valve on poisonous gases for this reason.  We pamper our specialty gas cylinders. They are filled in a separate plant at our facility in Pittsburgh. They undergo unique cylinder prep like moisture-eliminating bake outs. And they are a cylinder population all their own, separate from our industrial gas cylinder fleet. Why? Because our specialty gas customers deserve and demand elite quality and purity that is, well, special.
