Precautions for Solenoid Valve Installation

The solenoid valve is a valve that uses an electromagnet to control the movement of the spool. Solenoid Valve is an industrial equipment controlled by electromagnetic, used in industrial control system to adjust the direction, flow, speed and other parameters of the medium. There are many types of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used are check valves, safety valves, directional control valves, and speed control valves.

1. First check whether the solenoid valve is consistent with the selection parameters, such as power supply voltage, medium pressure, pressure difference, etc., especially the power supply. If it is wrong, the coil will burn out. The power supply voltage should meet the fluctuation range of the rated voltage: AC +10%~-15%, DC +10%~-10%, and the coil components should not be disassembled in normal times.

2. Before taking over the pipe, flush the pipe to remove the metal powder, sealing material residue, rust, etc. in the pipe. Pay attention to the cleanliness of the medium. If the medium is mixed with dirt, impurities, etc., which hinder the normal operation of the solenoid valve, a filter or screen should be installed in the pipeline.

3. In general, the solenoid coil components of the Gas Solenoid Valve should be installed vertically upwards and installed vertically on the pipeline horizontal to the ground. If it is required to be installed on the side due to space constraints or working conditions, it should be mentioned when ordering. Otherwise, the solenoid valve may not work properly.

4. Manual shut-off valves should be added before and after the solenoid valve, and a bypass should be provided to facilitate the maintenance of the solenoid valve when it fails.

5. Solenoid valves are generally directional and cannot be installed reversely. They are usually used on the valve body to indicate the flow direction of the medium, and install in the direction indicated by the →. However, it can be reversed in the vacuum line or under special circumstances.

6. If the medium will cause water hammer, you should choose a solenoid valve with waterproof hammer function or take corresponding preventive measures.

7. Try not to keep the Explosion Proof Solenoid Valve energized for a long time, which will easily reduce the service life of the coil or even burn the coil. That is, the normally open and normally closed solenoid valves are not interchangeable.

8. A trap should be installed on the inlet side of the solenoid valve for steam, and the connecting pipe should be inclined.
