AAK hydraulic pressure relief valve with consistent geometric tolerance

Henry is a purchaser of a hydraulic power unit manufacturer in the United
States. He almost lost his job when he purchased the hydraulic pressure relief
valves in the first time after just joining the company. AAK high-precision
hydraulic pressure relief valves saved the job for him. Last October, one of
their African customers customized a batch of hydraulic power unit equipment
for use in African mining bases. The requirements of the equipment for the
hydraulic pressure relief valves used are that there is no abnormality within 1
year.

Henry contacted more than 10 hydraulic pressure relief valve manufacturers and
screened 4 samples from each of 4 factories. A month later, the engineering
department debugged these hydraulic pressure relief valves. Almost all
hydraulic pressure relief valves from every factory have unstable hydraulic
system pressure, but only the proportion is different. At first, the engineer
thought it was due to the installation of hydraulic pressure relief valves or
the problem of oil quality. After several commissioning, it was found that the
outlet pressure of hydraulic pressure relief valves was almost equal to the
inlet pressure. After disassembling the hydraulic pressure relief valves, it is
found that the geometric tolerance is out of tolerance due to the accuracy of
the main valve spool and valve hole. After knowing this, the boss thought that
Henry had a problem on the communication with the hydraulic pressure relief
valve manufacturers and asked him to solve the purchasing of the hydraulic
pressure relief valves with the manufacturers within 4 weeks.

Henry has made two rounds of screening for hydraulic pressure relief valve
manufacturers and emphasized the working conditions, but still no one can
achieve that every hydraulic pressure relief valve has no problem. He felt that
he was cheated. The water in the hydraulic pressure relief valve industry was
too deep. Henry found AAK hydraulic valve on Google and left a message on our
website: Can AAK get the geometric tolerance of each hydraulic pressure relief
valve consistent? After several rounds of e-mail communications, we learned
about what happened when he purchased hydraulic pressure relief valves for the
first time. We can only comfort him that he was misled by hydraulic pressure
relief valve manufacturers due to lack of experience. He can test the samples
of AAK hydraulic pressure relief valves. Three weeks later, AAK sent Henry 5
samples of hydraulic pressure relief valves. Their engineer tested each sample
3 times, and the hydraulic power unit equipment was normal. The boss praised
his emergency ability. Now Henry doesn't have to worry about losing his job.

We told Henry that according to the working conditions and drawings of this
hydraulic pressure relief valve, the accuracy of each hydraulic pressure relief
valve is required to meet the standard and be stable, which needs to meet two
points: one is the selection of materials, the other is the control of
machining accuracy and the error correction of accuracy in machining, which is
the key. AAK use the GILDEMEISTER turn milling compound machining center
imported from Germany. During the machining process of various parts of the
valve body, the central encoder can be used to measure the position and
compensate the errors caused by tool wear. The worktable adopts the static
pressure guide rail with pure static pressure load, which has strong bearing
capacity. At the same time, it has the c-axis position detection technology
with double reading heads that is not available in general equipment. The
positioning accuracy of c-axis can reach 5 arc seconds, while at present, most
hydraulic pressure relief valve manufacturers do not have this kind of
equipment.

AAK hydraulic pressure relief valves are produced by high-precision advanced
equipment. Welcome to have a small try!
