Thermostatic valves and balancing valves


IVAR’s thermostatic valves are available in several configurations and sizes and are manufactured to the highest industry standards at our facility in Prevalle, Italy, using the finest quality brass and then finished with a nickel-plating to provide a protective coating and an aesthetically pleasing look.

Each valve is shipped with a protective cap to safeguard the thread. The same cap is also used in quality control testing to ensure the complete closure of the valve and the proper calibration of the rated rise.  The thermostatic inserts can be inspected and the peroxide EPDM o-ring on the spindle replaced, even when the system is in operation. Replacement parts are available.

All IVAR thermostatic valves are machined to NPT requirements and can be used on traditional water and low-pressure steam radiators, as well as hydronic baseboard, panel radiators and towel bar warmers, and are compatible with any thermostatic head using an M30 x 1.5 fitting.


In two-pipe systems, Aside from the inlet valve, a balancing valve should be installed at the radiator outlet with shut-off and balancing functions. IVAR balancing valves are offered as a twin of the corresponding inlet valve and are available also in coaxial patterns. The pipe connection can be female or male NPT, while the radiator connection is the standard tapered seal.
