The importance of air supply for pneumatic valves

Pneumatic  valves are valves that are driven by compressed air and realize on/off or regulation control. Taking THEOBORN pneumatic valves commonly used in projects as an example, such as imported pneumatic ball valves, imported Pneumatic Butterfly Valves, imported pneumatic plug valves, imported pneumatic diaphragm valves, imported pneumatic control valves, etc., all require air source drive, and the quality of the air source directly affects the use of pneumatic valves. A good, stable, and high-quality gas source can extend the service life of pneumatic valves, so there are certain requirements for the quality of the gas source. The standard air source pressure for THEOBORN pneumatic valves is 4-7 bar, and a good air source pressure must be stable at 5-6 bar, especially for single acting pneumatic valves. Excessive pressure can cause the valve to fail to open. When multiple pneumatic valves are used simultaneously, the air compressor must have sufficient capacity to ensure that the pneumatic valves can be opened or closed simultaneously. The air must be cooled, filtered, and free of moisture and impurities. The air inlet of pneumatic valves should be equipped with three parts of air filtration: filter, pressure regulator, and oil filter. When transporting compressed air over long distances, it is recommended to install air storage tanks near the site to stabilize the air pressure. All gas pipelines and gas pipeline connections must not leak. Do not apply excessive force when installing pneumatic valves to avoid damaging components.

The quality of the gas source is a very important factor affecting the service life of pneumatic valves. Therefore, the quality of the gas source is crucial. What are the factors that affect the quality of the gas source? How can we improve the quality of the gas source to ensure the good operation of pneumatic valves? We refer to the THEOBORN pneumatic valve manual, which has received high praise from users, and provide answers one by one.
    The main factors affecting the quality of the compressed air:
    1. The air filter is not installed in front of the cylinder, which causes the impurities in the pipeline to enter the cylinder and wear the sealing ring of the cylinder piston. 
    2. The air filter in front of the cylinder is not cleaned for a long time.
    3. The filter installed in front of the positioner of the pneumatic valve is too coarse.
    Ways to improve the level of compressed air treatment:
    1. The filter with the filter screen is used, and the filter screen only needs to be removed and cleaned when cleaning.
    2. The instrument air source should be set up separately with an oil-free compressor.
    3. Use products with low air consumption. The air consumption of  pneumatic  valves varies greatly from product to product. The low air consumption not only allows the compressor to be small, but also the air flow rate can be low, and the Solenoid Valve is also less noisy.
