High Pressure Proportional Control Valve For Air Conditioning / Heating Systems


Proportional Control Valve Application


The BL-VA7150 and BL-VA3000 series valve actuators are straight-stroke drives that can be used with the BL-VG7000 series valve body to achieve media flow regulation in the pipeline. Widely used in air conditioning, heating systems, etc., can also be used with other valves through different connectors.


Proportional Control Valve Model Description


BL-VA7150: Floating point type, built-in 24VAC bidirectional reversible motor, accepting switch type control signals, providing incremental control.


Proportional Control Valve Characteristics


◆Synchronous reversible motor with low AC voltage, with hysteresis clutch protection.
◆With manual operation mechanism, it can be manually switched and debugged under abnormal conditions.
◆With timed shutdown function and software double protection function.
◆ Small travel limit switch is adopted.
◆ Flame retardant ABS engineering plastic cover.
◆ Valve position indicator.
◆ Suitable for straight stroke control valves up to 20mm.
◆No noise, large output torque.
◆ Easy installation on site.


Proportional Control Valve Electrical wiring diagram



Proportional Control Valve Intelligent debugging instructions


◆ Long press “Key 1”, “LED1” light is on, press “Key 1” again, “LED1” light will flash once and it will enter the automatic calibration procedure;
◆ Long press “Key 2” to switch between forward and reverse. The "LED2" light is on for a positive transition, and the "LED2" light is off-reverse;
◆ Press and hold “Key 3” to switch the voltage and current input. The "LED3" light is on the 0-10V voltage, and the "LED3" light is off at 4-20mA;
◆The driver and valve body have been connected into one factory product. The user does not need to perform the stroke calibration. The driver and the valve body have been disassembled. The wiring must be calibrated to ensure that the valve operates accurately according to the given signal.
◆Note: Analog intelligent and digital models cannot be used at the same time, that is, when connected to analog intelligent type, 3-4 and 2-4 cannot be connected to AC24V. In the connection type, 4-5 cannot be connected to AC24V.
