Regulating valve, for hot water circulation system in multi-storey building, has housing fitted with regulating capsule with two thermostat elements controlled by circulated water temperature

摘要

Regulating valve (1) has housing (2) fitted with regulating capsule (8) with 2 thermostat elements (10,11) controlled by circulated water temperature, for opposing adjustment of 2 regulating pistons (12,13) cooperating with valve seat ring (14) with flow opening (17) between entry and exit channels (4,6) of valve housing, for regulation of water flow rate for disinfection of circulation system at water temperature of between 70 and 75 degrees C. A setting device allows pre-setting of the upper regulating piston for selection of the required water temperature with a maximum water flow rate.
