Power supply voltage: DC12~127V AC24~380
Connection methods: internal thread, external thread, flange
Leakage: Zero Remarks: Special large-diameter valves can be customized, with a maximum diameter of DN500 (mm).
Normally closed: When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is opened, and the main piston is pushed by the medium pressure to open the main valve port, allowing the medium to flow. When the coil is powered off, the main valve port closes and the medium is cut off.
Normally open: When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is closed, and the main piston is pushed by the medium pressure,
2、 Installation instructions for manual fuel solenoid valve:

During installation, the solenoid valve coil should be facing upwards and kept in a vertical position. The arrow or mark on the solenoid valve should be consistent with the flow direction of the pipeline and should not be installed in areas with splashing or leaking water.
2. The working medium of the solenoid valve should be clean and free of particulate impurities. The dirt and filters on the surface of the solenoid valve components should be cleaned regularly.
3. When the solenoid valve malfunctions, it is best to install a bypass device in order to isolate the solenoid valve in a timely manner and ensure the normal operation of the system.
4. In the pipeline system, the diameter of the solenoid valve installed on the branch should be smaller than that of the main pipeline valve.
5. Before installing the solenoid valve, the pipeline must be cleaned thoroughly. It is recommended to install a filter before the solenoid valve and a drain valve in the steam pipeline.
6. The solenoid valve should not be installed in a low concave part of the pipeline to avoid hindering its operation due to steam condensation, impurities, etc. settling inside the valve.
7. Ordinary solenoid valves cannot be used in explosive hazardous environments.
8. In the case of insufficient rigidity of the pipeline, it is recommended to fix the pipeline in front of the solenoid valve with a bracket to prevent vibration caused by the operation of the solenoid valve.
9. Before installing the solenoid valve, it is important to carefully read the product solenoid valve label, carefully read the instruction manual for the solenoid valve, and determine whether the solenoid valve product meets the usage conditions.
10. Pressure gauges need to be installed on the pipelines before and after the solenoid valve to observe the pipeline pressure.
3、 Maintenance and use of manual fuel solenoid valve:
1. It is recommended that the user unit assign a dedicated person to be responsible for use and maintenance.
2. After the installation of the solenoid valve, it needs to be tested several times with the medium and confirmed to be normal before it can be put into formal use.
3. Regularly clean the dirt inside and outside the valve and the suction surface, and be careful not to damage the sealing surface.
4. When the solenoid valve is not in use for a long time, the manual valve in front of the valve should be closed. When it is restarted, the steam solenoid valve should drain the condensed water and perform several trial operations. It can only be put into use after the switch is normal.
5. When the solenoid valve is removed from the pipeline and not in use, the internal parts should be wiped clean and stored with compressed air.
6. When used for a long time, if the seal between the piston and the valve seat is not good, the sealing surface of the piston can be re ground and now ground with the valve seat.
7. When working, pay attention to the pressure gauges before and after the valve, and ensure that the working pressure does not exceed the rated pressure. The working pressure difference must be within the rated pressure difference range. When the working pressure exceeds the rated pressure or the working pressure difference exceeds the rated pressure difference, the solenoid valve should be stopped and the front and rear manual valves should be closed to prevent the solenoid valve from exploding and leaking.
