Shanghai Bolufu Automation is a professional manufacturer of electric valves. The products are sold to related industries in many industries such as chemical, petroleum, tap water, pharmaceutical, solar photovoltaic, metallurgy and water treatment. The products are deeply trusted by old customers. Due to its many design features, electric valves have created their unshakable market competitiveness. Here we compare pneumatic and hydraulic valves to illustrate the advantages of electric valves:
The electric valve actuator is easy to connect with the computer, and it is more suitable for management with new electronic information technology; the failure rate of the electric valve is relatively low, and the maintenance cost is also relatively small. The electric valve can transmit signals over long distances. The required cable laying is more convenient and flexible than the air pipe or liquid pipe, and it is convenient for line inspection. The electric valve does not need special air source and air purification devices. Even if the power is suddenly turned off, the original execution position can be maintained.
Features of electric valve: (1) It is designed and manufactured by adopting the new structure of medium-line valve plate and short-structure steel plate welding. It is compact in structure, light in weight, easy to install, small in flow resistance and large in circulation. It avoids the influence of high temperature expansion and is light in operation. (2) There are no connecting rods, bolts, etc., which are reliable in operation and long in service life. Can be installed in multiple stations, independent of the flow of media.
When we use electric valves, we will inevitably encounter some valve problems, sometimes when the electric valve is energized, and the valve does not work properly. This makes us feel uncomfortable in the absence of familiarity. Measures. Next, our Shanghai Bolloff self-control valve is to analyze the problem of electric valves.
Is the power supply line normal, reconnected, or there is a problem with the wiring socket. There is a problem in preventing the power supply wiring of the valve from being firm, and the electric valve cannot work normally. It is also possible that the positive and negative poles of the power supply are confused. If such problems occur, they can be adjusted in time. Check the coil to see if there is any off-welding. Is there a short circuit? If you find a problem, you must replace the coil. Observe the fluid temperature and find that the temperature is too high, please replace the corresponding electric valve in time. Observe the working pressure difference. If the pressure difference is too large, adjust the pressure difference immediately until the symmetrical valve product is replaced.
Check whether the product is aging, the fluid viscosity is high, the frequency is too high, etc. In this case, it is recommended to replace the product. Check the main spool and moving iron core of the electric valve, and check whether there is any jam. If it is necessary to clean and clean it, replace it with a seal and install the filter immediately, because of the possibility of impurity deposition. If you still don't understand, you can call us at Bolloff. Professional for you.

Musk Xylene was once the most widely used of the "nitro-musks", but its use has declined sharply since the mid-1980s due to safety and environmental concerns. Itsexplosiveandcarcinogenichazards are recognized to be borderline, and musk xylene is a useful example of the lowest level of such risks which need to be taken into account.
