The Cirval is a lever-operated gas pressure regulator controlled by a diaphragm and setting spring which controls the valve. Mainly used for medium and low pressure natural gas distribution networks, as well as commercial and industrial applications. It should to be used with previously filtered non-corrosive gases. According to the European Standard EN 334, it is classified as Fail Open. The Cirval is Hydrogen Ready for NG-H2 blending.
