  • The Hydraulic Pressure Reducing Valve Changed Completely After Aak Took Over Order - China

    price: 100.00 Dollar US$

    Recently, I received the second re-order of a hydraulic pressure reducing valve from French client Chinning.

    I still remember when I first met Chinning in 2020, Chinning purchased hydraulic pressure reducing valves in a hydraulic valve factory and encountered quality complaints from her customers.

    The hydraulic pressure reducing valve was deformed in less than 3 months, and some valve spools and valve sleeves were seriously worn.

    More and more customers began to return goods, and the old suppliers did not cooperate with her work.

    Chinning had a big headache at that time, and the boss kept putting pressure on her to find a hydraulic valve manufacturer with exquisite quality as soon as possible.

    Chinning did not find a new hydraulic valve manufacturer very smoothly.

    Because her hydraulic pressure reducing valve had a special use scenario and required high hardness of materials, it was unbearable for ordinary factories.

    At the same time, under the environmental protection policy of 2019, many previous heat treatment and processing factories were shut down, so the supply supporting system was disrupted, and the heat treatment and processing of many hydraulic valve manufacturers could not keep up.

    Chinning found us AAK HYDRAULIC VALVE on Google by chance.

    Chinning's first question message on our website was "how does AAK ensure the service life of hydraulic valve products"? We didn't answer directly, but asked her if the hydraulic valves you purchased had the problem of deformation and rapid wear.

    She also replied quite frankly that she should find a hydraulic valve manufacturer that paid attention to the service life of hydraulic valves in the fastest time.

    I sent her several samples of hydraulic pressure reducing valve and told her that different parts of our hydraulic pressure reducing valve have different material hardness standards, and some could reach about 50-55HRC or higher.

    There is even no problem with 65HCR with special requirements.

    The service life of hydraulic pressure reducing valve is our hard index.

    More than one week after we sent out the samples of hydraulic pressure reducing valve, we received Chinning's email, including the drawings of hydraulic pressure reducing valve and the hardness requirements for various components.

    She asked whether we could produce this hydraulic pressure reducing valve? I told her that his hydraulic pressure reducing valve is not difficult, but just the working scene is some special.

    As long as the heat treatment process is a little unique, it could 100% ensure her requirements.

    The long service life of hydraulic valve is the most critical.

    AAK HYDRAULIC VALVE has controlled a heat treatment plant for 10 years in order to do a good job in heat treatment.

    The quenching and tempering heat treatment of this hydraulic pressure reducing valve material is sensitive to temperature.

    If the temperature is too low, the hardness is not enough, and it is easy to deform.

    On the contrary, it will lead to fracture.

    Only our proprietary heat treatment process can accurately grasp the appropriate temperature under the operation of experienced masters.

    AAK can also select the corresponding heat treatment process and determine the temperature range according to the different operating conditions of the hydraulic pressure reducing valve to ensure the service life of the hydraulic pressure reducing valve.

    Maybe there is no second hydraulic valve manufacturer with this ability in Ningbo, and the service life of AAK hydraulic pressure reducing valve exceeds 90% of its peers.

    The service life of AAK hydraulic pressure reducing valve is exquisite.

    You can also try a small order.
