Valves for Hydrogen Applications
Richards Industrials is the parent company to Equilibar and LowFlow Valves.
Equilibar® dome-loaded, multiple orifice back pressure regulators work in a different way, providing solutions for demanding fluid control challenges. They are easily automated and respond in milliseconds to accurately maintain control, making them ideal for challenging electrolysis and fuel cell applications. Their unique design allows them to precisely control pressure across a wide range of flow rates for gas, liquid and mixed phase fluids.
LowFlow Valve is an industry leader in precision fractional flow produced used to control the flows of liquids and gases across a diverse range of industrial applications. They are designed to control pressure or flow at tight tolerances while under extreme circumstances.
