Imported Solenoid Valve with Signal Feedback
Overview of Imported Solenoid Valve with Signal Feedback The solenoid valve with signal feedback is developed to achieve remote automatic control and to observe whether the solenoid valve is in normal working condition at any time. valve. It is based on the valve itself integrating a signal feedback device, which is automatically controlled by the system. When the solenoid valve is opened and closed, a power signal will be fed back to the system to monitor the operating status of the solenoid valve. This signal feedback solenoid valve has long been used in remote automation control.
The imported solenoid valve with signal feedback features unique design and medium non-contact signal feedback. The signal feedback is sensitive and can reliably indicate the opening and closing of the valve. It is especially suitable for closed-circuit systems with a high degree of automation. The solenoid valve with signal refers to the characteristic application of each series of solenoid valves, which can reflect whether the solenoid valve is in an open or closed state.
Principle of imported solenoid valve with signal feedback Working principle The signal feedback principle of solenoid valve imported from Olshen, Germany, when the coil When energized, the moving iron core is attracted, causing the main valve plug to move upward due to the pressure difference, opening the main valve port, and at the same time driving the moving magnet away from the sensor, which outputs a ~ DC signal to the control center. vice versa. Signal feedback When the solenoid valve is opened, the signal common line and the open signal line are connected. When the solenoid valve is closed, the signal common line and the off signal line are connected
Imported solenoid valve with signal feedback installation | maintenance
Solenoid There are three lead wires in the valve lead-out cable, one of which is the ground wire and the other two are working wires.
The inside of the pipeline should be cleaned before installing the solenoid valve.
On-site installation must be carried out in accordance with the relevant provisions of the National Electrical Safety Regulations for Explosion-proof Hazardous Places.
The solenoid valve is grounded internally and externally and must be solid and reliable.
When repairing the solenoid valve, the power should be cut off and the cover opened. Non-electrical personnel are not allowed to disassemble the electrical components of the solenoid valve
The solenoid valve should be installed vertically, with the coil on top.
When installing the solenoid valve, please note that the arrow on the valve body must be consistent with the flow direction of the medium.
When there are impurities in the solenoid valve, a high-density filter must be installed in front of the inlet end.
