Further Cooperation

The solenoid valve consists of two main components: a solenoid and the valve body. The valve body contains the input and output ports, and the solenoid is connected to the valve body once it is installed in the pipe.
① To allow for cooling, sufficient space must be maintained around the valve. It is recommended to install the valve in a dry and ventilated environment as during usage, the valve does get hot.
② Most solenoid valves can be used in one flow direction only. Be aware of the flow direction of the medium when installing the valve. An arrow on the valve body often indicates the correct flow direction.
③ The pipes on both sides of the valve must be securely fastened. Use a wrench for both the valve and the pipe while tightening. Prevent unnecessary stresses in the system.
Valves/Sensors/Switches/Solenoid Valves: Usage Precautions




1. Select appropriate solenoid valves according to their application environment, and do not mix them. For example, if you want to work in a highly corrosive environment, you should choose a corrosion-resistant solenoid valve; Another example is that the viscosity of the fluid flowing through is large, so the solenoid valve with high viscosity should be selected. In short, the solenoid valve shall be correctly selected before use.
2. The solenoid must be installed correctly. During installation, pay special attention to the arrow on the valve body, which shall be consistent with the flow direction of the medium, and no reverse differential pressure is allowed in the pipeline.
3. Pay attention to the operating voltage of the solenoid valve. The solenoid valve is divided into an AC solenoid valve and a DC solenoid valve according to the type of working voltage. AC is generally AC220V, and the DC solenoid valve is generally DC24V. Connect the correct working voltage, otherwise, the coil will be burnt. At the same time, to ensure the stability of the working voltage, the allowable deviation range of the working voltage of the general AC solenoid valve is - 15%~+10%; The allowable deviation of the DC solenoid valve is:+/- 10%. If necessary, pressure stabilization measures can be taken.
4. The electrical plug of the solenoid valve shall be reliably connected to the valve coil. The valve plug is generally equipped with fastening screws, which should be sown and tightened. Otherwise, mechanical vibration will cause the plug to shake, resulting in the fluctuation of the working voltage of the valve, which is likely to cause equipment malfunction or solenoid valve damage.
5. The medium pipe shall be kept clean and free of impurities. Otherwise, the solenoid valve core will jam and the equipment will act abnormally. Generally, a filter should be installed in front of the valve, and the filter screen should be cleaned and replaced regularly.
