This auction is for 4 new valves that came from the closing of a plumbing warehouse. below is some info from the Watts website. Shipping to USA/Canada is included. Please note that these valves have check valves and filters that the 1170 valves don't have and are approved for use in more places.
Series 1170C
Hot Water Temperature Control Valves
Sizes: 1⁄2" – 1" (15 – 25mm)
Series 1170C Hot Water Temperature Control Valves are specifically
designed for mixing hot and cold water in hot water supply
systems. They can be used for a variety of applications to reduce
the temperature of the hot water from the water heater and are
ideal for radiant heat applications. This series features a “double
throttling” design which combines the control of the hot and cold
water to provide a sensitive response to changes in water temperature
passing through the mixing chamber.
These valves also provide additional safety as they restrict mixed
water out to a drip upon loss of cold water supply to the valve.
As an added feature, the 1170C-M2 series incorporates check
valves and filter gaskets in both the hot and cold water inlets to protect
against cross flow. Available with threaded (-UT), solder (-US),
PEX, (-QC) Quick-Connect or CPVC connections.
Features
• Bronze body construction
• Solid wax hydraulic principle thermostat assures dependable
mixing of hot and cold water
• Thermostat controls both hot and cold water
• Solder, thread, PEX, Quick-Connect or CPVC end connections
available
• Integral check valves
• Locking cap
• Filter gaskets
Specifications
A Hot Water Temperature Control Valve shall be installed on
water heating equipment to provide tempered water to supply
piping. Valve shall have a bronze body, include integral check
valves and operate so the thermostat controls the cold and hot
water ports. The valve shall be provided with solder (-US),
threaded (-UT), PEX, (QC) Quick-Connect or CPVC connections.
Valve shall be CSA B125 certified and ASSE Standard 1017 Listed.
Valve shall be a Watts Regulator Company Series 1170C-M2.
†WARNING
Watts Hot Water Temperature Control Valves cannot be used
for tempering water temperature at fixtures. Severe bodily
injury (i.e., scalding or chilling) and/or death may result depending
upon system water pressure changes. ASSE standard 1016,
ASSE 1070 listed devices such as Watts Model L111, USG or
MMV-M1 should be used at fixtures to prevent possible injury.
The Watts Hot Water Temperature Control Valves are designed to
be installed at or near the boiler or hot water heater. They are not
designed to compensate for system pressure fluctuations and
should not be used where ASSE 1016 and ASSE 1070 devices
are required. These WATTS valves should never be used to provide
“anti-scald” or “anti-chill” service.
When installing the Model 1170C-M2 valves in a radiant heat
application, the components of the radiant heat system must be of
materials with a construction capable of withstanding the high limit
output temperatures of the heating boiler. If you are uncertain as to
the product's adaptability for your application, please consult an
authorized representative before installing or using the product.
