Actuator for flanged regulating valves - 24 V Caleffi 636

Actuator for flanged regulating valves - 24 V Caleffi 636

Regulating valves may be used in the closed circuits of heating and cooling systems, to control low 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 utility. They have one regulation port with an equal percentage characteristic and one by-pass port (three-way valves) with a linear characteristic. This adjustment characteristic guarantees the best possible system response to the various load conditions. They can be used in conjunction with proportional actuators with a 0–10 V, or 2- or 3-point control signal, depending on the requirements of the thermal load to be controlled.
