Balancing and control devices

Static balancing valves are hydraulic devices used to accurately adjust the flow rate of the thermal medium supplying the terminals in a system manually.

Dynamic balancing valves maintain the flow rate of the thermal medium at a constant level, even when the differential pressure conditions vary in the hydraulic circuit where they are installed. They are used to automatically balance the hydraulic circuit to ensure the design flow rate to each terminal.

The differential pressure regulating valve keeps constant, at the set value, the difference in pressure existing between two points of a hydraulic circuit.
The differential by-pass valve ensures a flow recirculation proportional to the number of valves being closed, limiting the maximum value of the differential pressure generated by the pump.

Regulating valves may be used in the closed circuits of heating and cooling systems, to control the flow rate (two-way valves) and to control temperature by mixing the primary circuit medium with the system return medium (three-way valves) in order to obtain the desired flow temperature to the user.

LUG and WAFER type butterfly valves are used in the closed circuits of heating and air-conditioning systems as zone or shut-off devices.

The mixing valves regulate the central heating system by mixing the boiler outlet water with the return water from the system in order to obtain the desired flow temperature at the point of use.
