SWEAT CONNECTIONS
CAUTION
• Valves must be in the fully-open position before attempting to
solder the ends.
Soldering a valve in the closed or partially-open position may
cause damage to internal components, resulting in valve leakage
and property damage.
Make sure the valve is installed in the correct direction of flow (refer
to applicable flow direction arrow on the valve body) and that the
valve is in the fully-open position before attempting to solder the ends.
Connections must be soft soldered with 95/5 (95% tin, 5% antimony)
type solder. The valve body must be heat sinked with a wet cloth
or putty at the closest joint to protect internal components, and the
flame must be directed away from the center of the valve body. DO
NOT exceed the temperature rating of the valve (250°F/121°C). Valve
bodies must be allowed to cool to room temperature before attempting
operation.
THREADED CONNECTIONS
Make sure all threaded connections are clean and free of any burrs.
Apply PTFE thread sealant tape or pipe dope to the external threads
of all threaded pipe connections. DO NOT use a combination of PTFE
thread sealant tape and pipe dope. DO NOT get any tape, dope, or
other foreign material into the flow path. NOTE FOR CONNECTING
TO FEMALE NPSM SWIVEL ENDS OF COIL HOSES: DO NOT use
PTFE thread sealant tape or pipe dope on any NPT threads connecting
into the female NPSM swivel end. Tape or dope may prevent proper
tightening of the threaded connection, reducing gasket compression.
UNION-TYPE ADAPTERS/CONNECTIONS
The o-rings in union-type adapters/connections must be lubricated
with Victaulic Lubricant or silicone to prevent the o-ring from pinching
or tearing during installation. Tighten union-type adapters/connections
hand-tight, then apply an additional quarter turn. DO NOT over-tighten
the connection.

COIL COMPONENT INSTALLATION
1. Connect the supply side of the Series 78Y Strainer/Ball Valve
Combination or Series 78T Ball Valve to the feed pipe via standard
threading or sweating practices, as described previously. Make
sure the applicable flow direction arrow on the valve body is facing
the direction of flow and that the valve body is rotated to the
desired position. NOTE: For effective operation, air vents must be
positioned at the highest possible location and must point upward.
2. If using coil hoses, make the connection to the coil first. Connect
the coil hose to the Series 78Y or Series 78T outlet union joint.
Ensure the o-ring is in place on the Series 78Y or Series 78T body.
Apply a thin coat of Victaulic Lubricant or silicone to the o-ring.
Refer to the “Coil Hose Installation” section for details on bend
radius specifications and additional installation requirements.
3. Connect the outlet of the balancing valve to the return pipe via
standard threading or sweating practices. NOTE: In order to obtain
accurate differential pressure measurements, turbulence should
be minimized. Refer to the installation instructions supplied with
the applicable valve.
4. Connect the coil hose (if applicable) to the inlet of the Series 78U
Union Port Fitting.
NOTICE
• Generally, between the male union outlet of the Series 78U and
the inlet of the balancing valve, there is a customer-specified
Automatic Temperature Control (ATC) Valve.
• Ensure that the ATC valve contains the correct inlet and outlet
sizes. Cutout lengths, etc. will need to be determined on a
case-by-case basis, depending on the type of ATC valve being
installed.
• If ATC valves are sent to Victaulic for inclusion in kits, verify that
the appropriate ATC valve is installed for the particular hook-up
to ensure proper design flows and performance.
• Refer to the instructions supplied with the ATC valve for
complete installation and maintenance requirements.
