For balancing hydraulic pressure in heating installations consisting of multiple circuits and pumps. FlexBalance Plus hydraulic balancers are supplied with an automatic air vent, a dirt chamber and a connection for a temperature sensor. The sensor can be connected using an immersion pipe (G ½"). The use of our patented PALL-ring technique enables a better response, returns higher efficiency, decreases total built-in height and shares its deaeration and dirt separation benefits.
