STEP ONE GETTING READY
Check the contents of this package. If any of the items listed below are missing or damaged, please refer to the Limited Warranty
and Product Return Procedure on the back of this brochure and contact your wholesaler or local tekmar representative.

STEP TWO MOUNTING
Note If types 024-026 are assembled and welded “in place”, the flap assembly must be removed from the valve body when welding
since excessive heat will damage the internal rubber seals. Also, do not use the valve body to "square" the flanges.
The tekmar 4 – Way Mixing Valves 016 - 026 mix supply water from a source with water returning
from a system. The valve can be automatically operated by utilizing a tekmar Actuating Motor and
a floating action control signal. This precision valve is manufactured to the highest quality standards
for a long trouble free service. It is designed for use in closed loop hydronic systems with properly
treated water. The valve provides a maximum of 1% leak through rate to allow for water expansion
during temperature changes. The valve ports are characterized to provide a proportional water
temperature change relative to the scale on the face plate of the valve.
When the valve flap is in the fully closed
position, 100% of the boiler supply wa-
ter is returned to the boiler and 100% of
the heating system return water is sup-
plied to the system. When the valve flap
is in the fully open position, 100% of the
boiler supply water enters the heating
system and 100% of the heating system
return water returns to the boiler. Mixing
of the water takes place when the valve
flap is in an intermediate position.
