  • The Original Manufacturer Shifted Responsibility Of Hydraulic Pressure Control Valve - China

    price: 100.00 Dollar US$

    Lateef, from Sweden, has been engaged in the procurement of hydraulic valves for 3 years and has been quite successful.

    Last year, however, he stumbled due to a hydraulic pressure control valve used in a hydraulic climbing vehicle.

    At the beginning of last year, their hydraulic climbing car was complained by customers that it was unable to rise.

    During after sales service, it was judged that the hydraulic pressure control valve was abnormal, and must be replaced.

    The original manufacturer refused to be responsible, because it has passed the 1 year warranty period.

    Lateef was embarrassed after checking, because after the hydraulic pressure control valves were shipped from the original manufacturer to their warehouse, their hydraulic climbing cars were delivered to the customer 4 month later, so the equipment was still within warranty.

    The boss was unhappy, Lateef was helpless.

    He tried to raise the warranty period of the hydraulic pressure control valves to 24 months to source new hydraulic valve manufacturers, but no reply from more than 10 manufacturers that he contacted.

    Lateef went from helplessness to anxiety.

    Lateef found AAK on B2B and left a message on AAK website: How long is the warranty period of hydraulic pressure control valve? I needed him to provide us drawings for discussion.

    According to his hydraulic pressure control valve drawing and working condition requirements, it is actually the standard part of SUN hydraulics.

    AAK has this procedure.

    I asked why he requires a 24 months of service life for the hydraulic pressure control valve, instead of requiring the number of durability times.

    Then he told me the above purchasing experience and sent me several hydraulic pressure valves from the original manufacturer.

    Our engineer found during disassembly that some valve spool cylindrical surface and conical surface, as well as the valve cage inner hole and conical surface are not concentric, which is a problem in accuracy and affects the function.

    The cone surface of some valve spool is worn, which affects the sealing, and the performance is not up to standard.

    Lateef was surprised to hear this, because no manufacturer gave him such analysis.

    I told him that AAK has a similar hydraulic pressure control valve.

    You can install it on the equipment for testing.

    If you can install it, you should not worry about customer complaints.

    He was surprised and happy.

    More than 10 hydraulic valve manufacturers had no reply, but AAK could send samples directly.

    2 weeks later, Lateef informed that the hydraulic climbing vehicle equipped with AAK hydraulic pressure control valve could work normally.

    He also asked about the warranty period of the hydraulic pressure control valve.

    I told him that AAK was benchmarking SUN, and its performance was 2 million times.

    As long as the equipment was used no more than 2500 times a day, there was no problem in 24 months.

    AAK hydraulic pressure control valve, benchmarking SUN, adhere to 3 aspects, Lateef is completely relieved.

    1 - The material is strictly selected.

    The valve spool is made of 20CrNi2MoV from Germany.

    The wear resistance of the valve spool is more than 3 times that of the material used by other hydraulic valve manufacturers.

    The other manufacturers may have the performance of 500, 000 to 1 million times, while AAK has the performance of 2 million times.

    2 - The precision is strictly controlled.

    The valve hole of this model is finely processed by American precision honing machine, and the precision of valve hole of other hydraulic valve manufacturers is 0.8 μm - 1.0μm, while AAK can be 0.6μm - 0.8μm.

    The precision is increased by 25% - 30%.

    3 - Strict inspection, equipped with a German Test high-precision measuring instrument for small micropore diameter, fully inspect each valve hole, while most hydraulic valve manufacturers only conduct sampling inspection randomly.

    AAK hydraulic pressure control valve, not only strict, you can also try a small order! AAK HYDRAULIC CARTRIDGE VALVES (350) 2022-09-15
