Double Stage Gas Regulator helps to reduce the high Inlet-supply pressure to low outlet or working pressure in two steps resulting in a more constant outlet-delivery pressure. The Gas Regulator is suitable for use where there is potential for large inlet pressure variation. The Gas Regulator is made using quality grade materials to ensure durability of use for a long time. The Double Stage Gas Regulator is especially useful for unattended operation, where the application demands a precise delivery pressure for gas service.
