Series: SCV
Description: Service Check Valves
Size Range: 1/8 to 3/4 in. (3 to 20mm)
Series SCV Service Check Valves are used in heating applications between
boiler piping and system components to facilitate the servicing of components
under pressure, such as thermal expansion tanks and float vents, without
draining the piping. As the component is threaded into the Service Check
Valve, the spring loaded valve opens to system pressure. As the component is
removed, the valve closes, maintaining system integrity while the component
is being inspected. Series SCV is not to be used on safety relief valves or
other safety or flow sensitive components.

Description: Hot Water Temperature Control Valves
Size Range: 1/2 to 1 in. (15 to 20mm)
Series 1170-M2, L1170-M2 Hot Water Temperature Control Valves are
specifically designed for mixing hot and cold water on hot water supply
systems. They can be used for a variety of applications to reduce the
temperature of the hot water from the system, 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.

120°F for model L1170-M2) with flow rates as low as 0.5 gpm and as high as 23
gpm. The superior flow characteristics of this valve provide accurate
temperature control to the requirements of ASSE 1017 across the rated flow
range. 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
