Dungs FRS Line Pressure Regulators
The Dungs FRS series gas pressure regulators are for reducing the line pressure running between a service regulator and an appliance pressure regulator.
FRS 7../6 Series Class I or Class II
The Dungs FRS series line pressure regulators are for lines running from a service regulator that require pressure reduction before reaching a gas appliance regulator. They are appropriate for high-efficiency appliances, high-turndown appliances, appliances using hot surface ignition or direct spark ignition, and other high-performance applications requiring a regulator. These regulators are suitable for dry natural gas, butane, air, propane, and inert gases. The regulator does not contain any non-ferrous metals and is applicable for gases containing no more than 0.1% by volume, dry H2S. A “dry” gas has a dew point lower than +15 °F, and its relative humidity is less than 60%.
