Although high-quality valves are available from a range of original equipment manufacturers (OEMs), valve performance issues will invariably occur. Over time, pressure swing adsorption (PSA) process pressures ranging from 300 to 700 psi contribute to equipment wear and result in leakage. This can impact process efficiency along with the volume and purity of the hydrogen end product. Leakage at the valve seat or stem also raises the risks of fugitive emissions and non-compliance with environmental regulations.
