1. DESCRIPTION
The Viking 6” Model G-6000 Dry Valve Riser Assembly consists of a small prole, light 
weight, pilot operated valve that is used to separate the water supply from the dry 
sprinkler piping, which is pressurized with air. The pilot operated valve combines an 
internal diaphragm assembly that is pressurized closed with priming water, an internal 
check valve to isolate the sprinkler system piping, and the Model A-1 Differential Valve 
located on the valve trim that allows the valve to operate upon loss of air pressure. The 
differential design of the Differential Valve allows an air supply of moderate pressure to 
control a higher water supply pressure. When the air pressure in the dry pipe system 
is reduced sufciently upon the differential valve due to a sprinkler head operation to 
destroy the pressure differential, the differential valve will open and relieve the prim-
ing pressure from the internal diaphragm assembly. The internal diaphragm assembly 
will compress, which will allow water to pass through the body of the valve and center 
of the internal check valve, entering the sprinkler system piping. The Viking Model 
G-6000 Valve is designed to be used with a water ow pressure switch and/or water 
motor gong. For systems that require an accelerator to increase the speed of water 
delivery, the Viking Model E-1 Accelerator shall be used.

4. INSTALLATION:
A. General Installation Instructions
1. For proper operation and approval, the valve must be installed in the vertical position as trimmed from the factory. DO NOT 
install horizontally or modify the factory assembled trim except as described in this technical data page. 
2. Viking recommends installing a 12” section of pipe directly above the G-6000 Dry Valve. Prior to valve maintenance, this sec-
tion of pipe may be removed to provide clearance for lifting the cover from the body.
3. The dry valve must be installed in an area not subject to freezing temperatures or physical damage. If required, provide a 
valve house (enclosure) with adequate heat around the dry valve and trim. Freezing temperatures and/or excessive pressure 
will damage the dry valve. When corrosive atmospheres and/or contaminated water supplies are present, it is the owner’s 
responsibility to verify compatibility with the Model G-6000 Dry Valve and associated equipment. 
4. The Viking Model E-1 Accelerator should be installed at the location indicated in Figure 1 when required by the installation 
standard or local Authority Having Jurisdiction.
