EBV Series Cast Iron Motorized Regulation Ball Valve

EBV series cast iron motorized regulating ball valve is applicable to central air conditioning system or heating system. According to the floating-point or proportional signal (DC 0/2~10V or DC 4/0~20- mA) from PLC, DDC and thermostat, the opening of the valve is adjusted to control the flow of the
medium in the pipeline and to meet the accurate control of the flow, pressure, and temperature.
