  • Hydraulic Relief Valves Performance Of 2 Million Times - China

    price: 90.00 Dollar US$

    The original hydraulic valve manufacturer can not solve the problem of the hydraulic relief valves for 2 times, AAK reassured Bauer with 2 million performances Bauer has been working in K & G company in Brazil for 6 years.

    His boss always trusts his work.

    Bauer and AAK have cooperated for 2 years.

    Two years ago, the marketing of a hydraulic windlass developed by K & G company focused on the selling point of "no repair in 1 year".

    However, 10 months after sales, some users complained that the windlass could not rise when it was just started.

    The problem lies in the leakage of the hydraulic relief valves.

    Per the manufacturer, some hydraulic relief valves had deviation during assembly, he was willing to replace the hydraulic relief valves for free.

    But after a few months, the same problem continued.

    The boss was dissatisfied, and Bauer felt the pressure and checked with other manufacturers of hydraulic relief valves, but still no solution.

    Bauer began to worry.

    Bauer emailed me to ask why the hydraulic relief valve leaks? This is a system problem.

    I suggested that he send us the drawings of the hydraulic relief valve, the hydraulic principle of the hydraulic windlass, and the actual samples of the leaked hydraulic relief valve.

    Our engineer disassembled the original hydraulic relief valves and found that the contact surface between the poppet and the valve body was worn.

    The leakage was caused by the weak impact resistance of the valve spool.

    I told Bauer that because the working condition of this hydraulic windlass is a little special, it has high requirements for the hydraulic relief valve, especially for the impact resistance of the valve spool.

    The manufacturing quality of the original hydraulic valve manufacturer is not poor, and the deficiency lies in the valve spool, which can be improved.

    Bauer had no confidence in the original manufacturer and asked AAK to replenish 50 hydraulic relief valves.

    After 45 days, AAK sent out the hydraulic relief valves and promised "no repair in 1 year".

    Last week, Bauer informed AAK by e-mail that for those hydraulic windlasses installed with AAK hydraulic relief valves, the customers no longer complained about abnormal starting.

    Bauer admired AAK for not only finding the "cause" but also fitting the right medicine to the case.

    He was relaxed and the boss was satisfied.

    In fact, it is not how strong AAK is, but the inertia thinking of many hydraulic valve manufacturers.

    They seldom consider the difference of hydraulic working conditions when deciding which hydraulic components to fix.

    AAK insists that every hydraulic relief valve is a new subject, from material selection to production.

    AAK uses 3Cr3Mo3W2V hot working die steel for this hydraulic relief valve spool, its mechanical stress is unique among many steels.

    Its hardness, strength and wear resistance are more than twice that of conventional valve spool materials, and it also has good thermal fatigue stability and corrosion resistance.

    Although it is difficult in the processing link, AAK still needs to choose the most suitable steel, even if the processing cost is 2-3 times higher.

    Because AAK can't make things that are not good enough, let alone supply them to consumers.

    Only in this way can we ensure that the hydraulic relief valve will not be impacted and eroded under special working conditions, and ensure the performance of 2 million times.

    AAK hydraulic relief valve, with a performance of 2 million times long service life, welcome to have a small try! AAK HYDRAULIC VALVES (343) 2022-09-08
