Return temperature limiters

Valves for return temperature limitation

Return temperature limiters are used in combined radiator and surface heating systems with closed circuits. The valves are available in reversed angle for return and straight for return versions. The integrated valve insert has a double plug that prevents unintentional overheating. In addition, the valve has a frost protection function. The Uni RTLH thermostats with connection thread M 30 x 1.5 and the Uni RTL thermostats with connection thread M 30 x 1.0 are suitable for the valves (see chapter “Return temperature limiter Accessories”).

Return temperature limiter sets

The return temperature limiter sets consist of the valve for return temperature limitation and the matching Uni RTLH thermostat.  The sets are available in reversed angle for return and straight for return versions, each with a white thermostat.
