Modulating Water Valves (Option)
The modulating control valve option
provides optimum control of hot and
chilled water flow in various heating
and cooling applications. They are
designed to provide sinusoidal valve
actuator travel and operate silently,
resisting water hammer.
The actuator on the valve is a 24V, 3-
point floating type. See Table 3 for more
technical data.
Isolation Valves (Option)
The isolation valves are two position
24V, spring return type. They provide
added control in heating and cooling
applications when used in conjunction
with the face and bypass damper.
On heating coils and two-pipe change-
over applications, the valve is a normal-
ly open type to prevent the coil from
freezing in case of power loss.
For cooling, the valve is normally
closed and opens when there is a call
for cooling. See Table 4, for more tech-
nical data.
