Motorized Proportional Control Valves
Electric Proportional Control Valve
An electric proportional control valve is a globe-type control valve with an electric motor (or solenoid) actuator that continuously adjusts its opening in response to a 0–10 V or 4–20 mA signal from a controller. As it does not require compressed air, it is widely used in building automation, heating, cooling and hot water systems.
2-way (flow control) and 3-way (mixing / diverting) models are offered with cast iron and steel body options in PN16 and PN40 pressure classes. Solenoid-actuated models respond within seconds, providing precise temperature control.
