present.
Mounting
The valve should be mounted in a weather protected area, if the actuator 1.
is not rated for outdoor use, in a location that is within the ambient limits of
the actuator. When selecting a location, allow sufficient room for the valve,
linkage, actuator, and other accessories and for service of the product.
The preferred mounting position for the valve is with the valve stem vertical 2.
above the valve body. Avoid mounting the valve so that the valve stem is
below horizontal.
For steam applications only, position the valve body so the valve stem and 3.
actuator are at 45° from vertical.
The two-way valves must be piped with the “A” port as the inlet and the 4.
“AB” port as the outlet. Mixing valves must be piped with two inlets ( “A”
and “B” ports) and one outlet (“AB” port). Diverting valves must be piped
with one inlet (“B” port) and two outlets (“A” and “AB” ports).
Valve-specific instructions are available on pages 2 and 3. 5.
