Hydraulic Valve Block 3 Types Of Pressure Test Standards - China

3 pressure test standards of AAK hydraulic valve block replaced 1 pressure test standard of peers, Andy no longer worries about losing customers Andy is one of our old customers of hydraulic valves in Germany.

He purchases hydraulic cartridge valves from AAK all year round.

Recently, he suddenly asked me some technical parameters of hydraulic valve blocks.

I was a little surprised.

After further communication, I learned that he started to purchase hydraulic valve blocks for the first time last year, but failed.

Andy purchased a batch of hydraulic valve blocks from a manufacturer who just produced hydraulic valves for him in the past.

Maybe this manufacturer didn't know enough about the hydraulic valve blocks.

After 100 hydraulic valve blocks arrived, there was a problem after sales.

According to the user's feedback, the pressure of the hydraulic valve blocks could not meet the system requirements, and was also unstable.

Most hydraulic valve blocks were required to be returned.

The manufacturer also said that these hydraulic valve blocks had been tested before leaving the factory.

Now these hydraulic valve blocks are stacked in the warehouse.

Andy regretted it so much that he was sad all day long.

According to the hydraulic valve block drawings, sample photos, and videos provided by Andy, I told him that the processing accuracy of the hydraulic valve block should still be flawed.

Although the original manufacturer also did the pressure test, he may not understand that there are 3 types of hydraulic valve block pressure tests, or even he just completed the pressure test on the test bench.

This is a common problem in pressure test of most hydraulic valve block manufacturers, but AAK never tests like this.

2 weeks later, I sent 10 samples of hydraulic valve blocks according to his drawings.

About 2 weeks later, Andy advised that when AAK hydraulic valve block was installed, the pressure parameters were consistent with the system requirements, and it was smoother and had more stable debugging than that of the original manufacturer.

Users liked it very much.

Andy disposed of the hydraulic valve blocks in the warehouse and asked us to replenish 100 pieces as soon as possible to fill the inventory.

I told Andy that the processing of AAK hydraulic valve blocks will not be falsified in terms of accuracy first and finally in the pressure test stage of hydraulic valve blocks will not be sloppy.

The pressure test is carried out directly in the hydraulic system, which is more consistent with the operating conditions than the test on the test bench.

At the same time, the test is determined according to the working pressure of the system.

However, most manufacturers cannot directly test the hydraulic valve block in the hydraulic system, and directly use the traditional process to test on the test bench.

The pressure test of AAK hydraulic valve block is divided into 3 types of standards.

Peers may not be able to master the 3 types of methods, and blindly use the test of 1.5 times the working pressure to test whether the pressure of the hydraulic valve block is stable or not.

We classify it in this way: for working pressure less than 16MPa, the test is 1.5 times; for the working pressure of 16MPa~25MPa, the test is 1.25 times of the working pressure; at the same time, for the working pressure of 25MPa~31.5MPa, the test is 1.15 times of the working pressure.

AAK uses 1.5 times, 1.25 times, 1.15 times to distinguish the only standard 1.5 times of its peers.

This detail not only has demons, but also money.

It depends on whether you can dig it out.

AAK hydraulic valve block, focus on details, more stable, welcome to try.
