Series SS009QT Stainless Steel Reduced Pressure Zone
Assemblies provide protection of the potable water supply in accor-
dance with national plumbing codes and water authority require-
ments. Series SS009 can be used in a variety of health hazard
installations whenever the downstream liquid is of a composition
which may damage bronze material or it is desirable to eliminate
trace elements of lead and copper. Typical applications are:
Industrial or plant use, medical/diagnostic equipment, reverse
osmosis systems, carbonated beverage machines, breweries/dis-
tillers, paper and pulp industry, chemical plants and aggressive
atmospheres. The SS009 series features two in-line independent
check valves, captured springs, replaceable check seats, corrosion
resistant internal parts and a hydraulically operated differential pres-
sure relief valve. All sizes are constructed with NPT body connec-
tions and are standardly furnished with vandal resistant EZ-TC Test
Cocks. Series SS009QT's are furnished with 316 Stainless Steel,
full port, investment cast, quarter turn ball valve shutoffs with 304
Stainless Steel tee handles.
Features

for corrosion resistance
• All wetted valve components — test cocks, ball valve
shutoffs, pipe nipples, body and cover, check modules and relief
valve assembly are made from "Lead Free" Stainless Steel or
Plastic construction
• Bolted on, top entry single access cover for ease
of maintenance
• Modular check construction featuring nonreversible checks with
captured springs for simplified servicing
• Top mounted vandal resistant EZ-TC test cocks provide easy
access for testing
• Stainless Steel EZ-TC test cocks include dust covers to protect
the threads from dirt, dust and insects
• EZ-TC Test cocks eliminate the need for tools and test fittings
• True line sized check modules open further allowing dirt and debris to
pass freely through the valve reducing fouling problems
• Check and Relief Valve Seats are replaceable without the use of
special tools
• Internal relief valve for right and left hand installations
Specifications
A reduced pressure zone assembly shall be installed at each noted
potential health hazard location to prevent backflow due to back-
siphonage and/or backpressure. The assembly shall consist of an
internal pressure differential relief valve located in a zone between
two independently operating positive seating check modules with
captured springs and silicone seat discs. Seats and seat discs shall
be replaceable in both check modules and the relief valve, without
the use of special tools. There shall be no threads or screws, in the
waterway, exposed to line fluids. Service of all internal components
shall be through a single access cover secured with stainless steel
bolts. The assembly shall include two resilient seated isolation
valves, four top mounted vandal resistant test cocks with dust cov-
ers, a protective stainless steel wye strainer with a 20 mesh screen
and an air gap fitting. The assembly shall consist of an investment
