Model F-1/F-2 Dry Valve Trim, Modular
The Viking Model F-2 Dry Pipe Valve is a latching differential valve used to separate the water supply from the dry pipe sprinkler system. The valve combines a positive latching clapper and air plate assembly with a differential air to water seat design. The latching clapper and air plate assembly provides a positive mechanical seal for the air pressure in the dry pipe system. The differential design allows an air supply of moderate pressure to control a higher water supply pressure. When the air pressure in the dry pipe system is lowered sufficiently to destroy the pressure
differential, the valve opens allowing water to enter the dry pipe system. The valve is also designed to operate a water motor alarm and/or an electric pres- sure alarm switch. The Viking accelerator can be used to speed the operation of the valve on large capacity systems or where faster action is required.
