NEW thermostatic compact valve TRV series with variable Kv setting

Thermostatic valves with fix Kv setting, series 378TRV, 379TRV, 1378TRV, 1379TRV, and those with variable Kv setting, series 388TRV,

389TRV, 1388TRV, 1389TRV are used as shut-off and control devices for heat emitters (radiators, fan coils, radiant panels, etc.) in heating and

air-conditioning systems. TRV thermostatic valves series are available in angle body and straight body configurations, with male or female thread

and should be installed on the supply pipe of the heat emitter. Connection to the heat emitter is through an O-RING sealed straight tailpiece with

use of a socket head wrench.


In combination with thermostatic or thermoelectric/electronic actuators, the new WATTS TRV valves with variable Kv enable precise balancing of

the hydraulic system, which results in cost savings. Pre-setting of the valve Kv is done by turning a ring under the handwheel in order to limit flow

passage. The adjustement can be simply made by hand without a tool. Six pre-set positions ( 1 to N ) are available for the setting of the correct valve Kv.
