Diverter and isolation valves

for panel radiators

3010, 3011, 3012, 3013 series

01036/12 NA

Function

Calefﬁ 301 series valves are installed on panel style radiators. They are

connected to the bottom supply and return ports, providing ﬂuid ﬂow to

the upper thermostatic valve built into the radiator. The center-to-center

dimension is 50 mm, which is the common standard for all brands of

panel radiators.

Two versions are available: Diverter style for one-pipe systems; Isolation

style for two-pipe systems. Both have two ball shut-off valves and come

as either a straight through ﬂow pattern for ﬂoor connections or angled

ﬂow pattern for wall connections.

The diverter style offers an adjustable by-pass to send 30% to 50% of

ﬂow toward the radiator, factory-set for 35%. In addition, the diverter

style contains a unique thermal break device in the return side (right leg)

to prevent undesirable ﬂow to the radiator due to thermo-syphoning

when the thermostatic valve is closed, no call for heat.
