A brief discussion on the role of directional valves in booster pumps

    What is the reversing valve in the booster pump used for

    This is a very small directional valve that contains a lot of big knowledge. Let's take a look at its appearance below

    So where is it located at the booster pump?


    The directional valve of the pneumatic booster pump is located inside the valve body and includes the valve body, valve cover, valve core, and O-ring; The reciprocating motion of the booster pump is achieved by the reciprocating motion of the reversing valve (striker), and the O-ring inside is a vulnerable part, especially when the air source of the air compressor is not clean or the moisture is too high, which will cause more and more impurities to accumulate inside the reversing valve, resulting in the wear of the sealing ring on the upper surface of the valve core, causing the booster pump to not work or work intermittently;

    The material of the O-ring must be heat-resistant, wear-resistant, corrosion-resistant, etc. Only by ensuring the quality of the O-ring can we provide an additional layer of care for the overall quality of our pneumatic booster pump;
