ON-OFF valves with thermoelectric actuator
Valve set, 2 or 3 ways, ON-OFF, with thermoelectric actuator.
The set includes connection pipes and holders.
Note: The main battery valve connection
is 1/2” (Kvs 2) for TL0 - TL1 - TL2 - TL3 sizes
and 3/4” (Kvs 3,5) for TL4 - TL5 - TL6 sizes,
the auxiliary battery valve connection is 1/2” (Kvs 2).
