Precautions for correct installation of Ball Valve

1. Read the product manual carefully before installation, check whether the product meets the usage requirements, remember the installation points, and make preparations.

2. Pay attention to the cleanliness of the medium. If the medium is mixed with dirt, impurities, etc. that will hinder the normal operation of the Ball Valve, a filter valve with a mesh of ≥60 mesh should be installed in the pipeline.
3. The Ball Valve should not be installed in a low recess in the pipeline, but in the discharge pipe of the container. Be careful not to lead it out from the bottom of the container, but should be installed slightly above the bottom of the container.
4. If the medium will cause water hammer, a Ball Valve with waterproof hammer function should be selected or corresponding preventive measures should be taken.
5. A Steam Trap should be installed on the inlet side of the steam Ball Valve, and the pipe should be tilted there.
6. Check whether the parameters marked on the nameplate are consistent with the parameters of the selected product. The power supply voltage should meet the rated voltage voltage fluctuation range: AC +10%~-15%, DC +10%~-10%. Coil components should not be disassembled at ordinary times.
7. Before taking over the Ball Valve, flush the pipeline with a pressure of 0.3MPa to remove metal powder, sealing material residue, rust, etc. in the pipeline.
8. Ball Valve are generally directional and cannot be installed backwards. Usually "→" is used on the valve body to indicate the direction of medium flow. When installing, it must be installed in the direction indicated by "→". However, our company may sometimes install it in vacuum pipelines or under special circumstances. Exceptions are made for reverse installation.
9. Make sure there is no leakage in the Ball Valve itself and the connection between it and the pipe.
10. Check the connection of the coil lead wires, especially when there are three lead wires.
11. Electrical components connected to the Ball Valve, such as relays, switches and contactors. The contacts should not vibrate when the valve is opened, otherwise the operation will be unreliable and the service life of the Ball Valve will be affected.
12. The electrical circuit must be connected to the corresponding insurance wire as a protection for the electrical circuit.
13. There should be a certain reserved space at the Ball Valve installation location to facilitate daily maintenance and regular repairs.
14. During installation, use a wrench or pipe wrench to fix the valve body, and then screw on the connecting pipe. Never apply force on the Universal Valve assembly to cause deformation, which will make it difficult for the Ball Valve to operate normally.
15. If the pipe rigidity is insufficient or there is water hammer, please fix the front and rear pipes of the valve with brackets.
16. When used in freezing places, the pipes must be protected with insulation materials or heaters must be installed on the pipes.
17. Installation posture: Generally, the Universal Valve components of Ball Valve should be vertically upward and installed vertically on pipes horizontal to the ground. If limited by space or working conditions require, they must be installed sideways like pipes in building sewers or installed upside down. Please mention it when selecting and ordering. Some products have special regulations, please install according to the instructions.
18. When taking over the pipe, be careful not to use too much sealing material. For example, when connecting with threads, the thread of the nozzle should be kept within the effective length, and the half pitch of the end should be chamfered with a file, and the sealing tape should be wrapped starting from 2 teeth from the end, otherwise excessive sealing tape or adhesive will enter the Ball Valve. inner cavity, and an accident occurs that prevents normal operation.
