Valve maintenance kit AMD-2

The TYCO Model AMD-2 Automatic Air Maintenance Device is an automatic, field-adjustable device that controls the on-off cycling of an air compressor. It is used to control the pressure in a dry pipe sprinkler system, preaction system, or dry pilot line of a dry pilot actuated deluge or preaction valve. The Model AMD-2 Device is utilized in applications requiring the use of a small, non-tank mounted compressor dedicated to system pressurization. The Model AMD-2 Device monitors system pressure and automatically cycles the air compressor on and off to maintain system pressure within preset limits. The Model AMD-2 Device features a Pressure Switch with integral unloading valve that automatically bleeds the pressure between the air compressor and the Model AMD-2 Device after the air compressor automatically shuts off. This feature prevents start-up of the air compressor under load. The Model AMD-2 Device is a re-designation for the Central Model DU-2, Gem Model F326, and Star Model S465.
