6. REGULATING VALVES
6.1 ON/OFF VALVES: 3-WAY WITH 4 WATER CONNECTIONS (H3A2-H3B2) OR 2-WAY (H2A2-
H2B2), 1/2”-3/4”, 230V, FOR 2 OR 4 PIPE SYSTEMS
The ON/OFF 3-way regulating valves with bypass and 2-way regulating valves are provided with thermoelectric actuator and
connection tubes. The direct water flow is closed by not supplying power to the actuator.
They are suitable for fan coils size 110÷328 and available also with 24V~ (H3B0, H2B0, H3A0, H2A0).
6.2 MODULATING VALVES: 3-WAY WITH 4 WATER CONNECTIONS (J3AM-J3BM) OR 2-WAY
(J2AM-J2BM), 1/2”-3/4”, 24V, FOR 2 OR 4 PIPE SYSTEMS
The modulating 3-way regulating valves with bypass and 2- way regulating valves are provided with modulating actuator
and connection tubes. The direct water flow is closed by not giving the 0-10V signal to the actuator.
They are suitable for fan coils size 110÷328.
