hammer.
• Approved for horizontal and vertical installation.
• Streamlined body design provides very low friction loss.
Product Description
Reliable Model G Swing Check Valves are low friction loss check
valves approved for use in fire protection systems. Typical applica-
tions include connections between public water supplies and pri-
vate fire systems, at the discharge from fire pumps, at gravity tank
connections and at fire department pumper connections. All Model
G Check Valves are provided with ½” NPT (R½) supply side and
discharge side connections (Item 12, Figure 1). Grooved end con-
nections provide fast and easy installation using listed or approved
mechanical grooved couplings. Rigid style grooved couplings can
be used for positive clamping to resist flexural and torsional loads.
Installation
The Model G Check Valve shall be installed in accordance with
NFPA 13, “Standard for the Installation of Sprinkler Systems,”
as well as the requirements of any authorities having jurisdic-
tion. When installed vertically, the direction of flow shall be up
through the valve (install with flow arrow pointed up). For hor-
izontal installations, the hinge pin must be located to the top.
Failure to follow installation instructions may void the warran-
ty and listing of the valve. Verify compatibility of the Model G
Check Valve materials with the water supply and the environ-
ment where the valve will be installed prior to installation. Do
not apply lubricants, sealants, or other chemicals to the clapper
seal or seat.

Note: Model G Check Valves may be damaged by excessively turbu-
lent water flow. Model G Check Valves should be installed a reasonable
distance from pipe transitions, such as pumps, elbows, expanders, re-
ducers, or similar devices. Typical piping practices suggest a minimum
distance of five times the pipe diameter for general use.

Maintenance
The owner is responsible for maintaining the fire protection sys-
tem in proper operating condition. Any system maintenance or
testing that involves placing a system out of service may elim-
inate the fire protection that is provided by the fire protection
system. Notify any required authorities having jurisdiction and
implement appropriate precautions prior to proceeding.
The Reliable Model G Check Valve shall periodically be given
a thorough inspection and test. NFPA 25, “Inspection, Testing
and Maintenance of Water Based Fire Protection Systems,” pro-
vides minimum maintenance requirements. Inspect the interior
of the valve and all components for corrosion, damage, and
wear at least every five (5) years. Replace any components
found to be corroded, damaged, or worn. Increase the fre-
quency of inspections when the valve is exposed to corrosive
conditions or chemicals that could impact the valve materials.
