  • Hydraulic Relief Valves Benchmarkes With Hydraforce - China

    price: 100.00 Dollar US$

    For the Hydraulic Relief Valve of same model as HydraForce, even price is 30% higher, Quentin still placed order with AAK Quentin is from Italy.

    He is a new purchaser of a company which has cooperated with AAK for 4 years.

    He is very aggressive, but the first purchase of hydraulic relief valves overturned.

    At the beginning of this year, a batch of excavators of their company needed hydraulic relief valves, which were standard parts of HydraForce.

    Quentin asked more than 10 hydraulic cartridge valve manufacturers, and chose one manufacturer that is 60% cheaper than HydraForce to place an order.

    Six months later, trouble began.

    A customer complained that the oil pipe of the excavator burst.

    The engineer realized that it was not just the problem of replacing the oil pipe.

    It was found through inspection that the hydraulic relief valve was sluggish during operation, resulting in the instantaneous formation of peak pressure in the system, which caused the oil pipe to burst.

    The inner wall of the valve hole of these hydraulic relief valves was worn.

    However, the manufacturer of the original hydraulic relief valves said that it was caused by the unclean hydraulic oil, which had nothing to do with them.

    Quentin was afraid to take responsibility and dared not report to his boss.

    Quentin was very nervous.

    He contacted several manufacturers of hydraulic relief valves, but no gain.

    Carter, another old purchaser, saw that he was at a loss and suggested that he has a try with AAK hydraulic valves.

    Quentin emailed me and asked if the program of this HydraForce valve was available.

    Only then did I know that his first purchase of hydraulic relief valve was not smooth.

    I sent him the pictures and technical parameters of the hydraulic relief valve.

    The next day, he asked me to deliver 50 hydraulic relief valves first to solve customer complaints urgently.

    Two weeks later, Quentin informed that the replacement work was completed and the excavator could work.

    Quentin said that although the price of AAK is 30% higher than that of the original manufacturer with hidden quality problems, it is still 30% cheaper than that of HydraForce, and the surface treatment of AAK hydraulic relief valve is more textured than that of HydraForce.

    I told him that AAK hydraulic relief valve not only has the appearance value, but also has the performance of no less than 2 million times.

    The reason why AAK hydraulic relief valve can be compared with HydraForce is that AAK insists on selecting the most suitable steel, even if the processing cost is 2-3 times more expensive, it should also choose the best.

    AAK can't do anything that is not good enough, let alone give it to users.

    We always adhere to the following 3 points: 1 - The material selection is "cleanliness".

    The A + material is used to replace the A material of the standard part.

    For example, 3Cr3Mo3W2V is used to produce the valve body of this hydraulic relief valve.

    Compared with similar steels, its hardness, strength, wear resistance and toughness have all improved to a new level.

    It ensures the impact resistance of the hydraulic relief valve during the working process of the system, and stands guard for the performance of 2 million times.

    2 - The selection of equipment is "guaranteed".

    The valve hole of the hydraulic relief valve is precision machined with Swiss high-precision honing machine, and the accuracy of the valve hole can reach 1.0μm, while most manufacturers of hydraulic relief valves are in the range of 2μm.

    3 - For surface treatment, AAK insists on using galvanized nickel alloy to replace the galvanized treatment of HydraForce.

    It is not only beautiful, but also textural.

    Quentin told me in private that in his conversation with me, he was more determined to do a good job in purchasing.

    This time, he solved the customer's complaints in time, and his boss was happy to see him.

    AAK hydraulic relief valve surpasses its domestic counterparts and benchmarkes with HydraForce.
