Electric Proportional Relief Valve , Two Way Electronically Controlled Proportional Valves
Proportional Relief Valve Description
BL-VA3102: Intelligent, can accept and feedback 0-10V or 4-20mA control signals, providing proportional control.
Proportional Relief Valve Characteristics
◆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.
