Valve
If you intend to control the valve with an outdoor temperature com-
pensator, we recommend installing the valve body within 20" (0.5 m)
of the OTC panel to simplify the wiring.
The valve must be oriented correctly towards the boiler
supply water in order to work correctly. Boiler supply water may
enter vertically from below, or horizontally from the left, or right of
the valve. Mixed loop supply exits the valve horizontally (left or
right) with bottom boiler supply, or from the top with left-handed
or right-handed boiler supply. The position indication scale must
not point to the floor.
A. Mount the valve at least 32" (0.8 m) above the return line to
prevent thermal siphoning. See Fig. 2.
Position the valve body so that boiler water enters the port
marked by the boss.
See Fig.4 for possible mounting orientations for the V5442,
and select the appropriate configuration.
B. Install the valve body in the pipes. Use NPT-to-sweat
adapters if installing on copper pipe. Unions are not required
for serviceability, but may speed installation.
Note: Threaded fittings must have pipe dope or Teflon™ tape
to prevent leakage.
C. Identify the mixed output port, and select the corresponding
range on the valve position indicator scale. See Fig. 3.
D. If using the valve manually, clip the stop pin from the molding
sprue on the handle and insert the pin in the hole, according to
Fig.3. Assemble the handle onto the valve.
E. For other valve orientations, use the manual handle to align the
position indicator on the valve's square drive socket with the
mixed output port. The mixed output will be either be 90°
counterclockwise or clockwise relative to the boiler supply
input port. Insert the stop pin into the appropriate hole on the
handle and assemble the handle to the valve body.
Refer to Fig.5 to 8 for piping options in various hydronic
systems.
