QDF Series Motorized Butterfly Valve -Midline Soft Sealing

QDF series midline soft sealing motorized butterfly valve is applicable to central air conditioning system and heating system. According to the output signal of floating-point type or proportional adjustment type (DC 0/2~10V or 4/0~20mA) from PLC, DDC and thermostat, the opening of the valve is adjusted to control the flow of the medium in the pipeline system. The
opening of the motorized butterﬂy valve is always kept within the set range to meet the accurate control of the ﬂow, pressure, and temperature in the pipeline system.
