The hydraulic directional valves produced by AAK adopts its own proprietary quenching and tempering heat treatment process, which can greatly improve the strength of the hydraulic directional valve, avoid deformation and wear of the hydraulic directional valve in the long-term use process, and significantly increase the service life. Perhaps there is no second comparable manufacturer in Ningbo like this. At most, 10% of the domestic hydraulic valve peers can compete.
In order to win orders, 50% of the hydraulic valve manufacturers do not do any heat treatment to the materials for the hydraulic parts. Although some hydraulic valve manufacturers insist on heat treatment, they can only be outsourced processing due to without equipment. There are also 20% of hydraulic valve manufacturers, who do not have a fixed outsourced processing place, so it is impossible to ensure the heat treatment quality, not to mention the stability. Due to these common problems in the hydraulic valve industry, the hydraulic valve will show many problems after being used for a period of time, such as product deformation and wear. Once the hydraulic valve is deformed, it will easily to be blocked and the service life of the hydraulic valve will be greatly shorten.
5 months ago, Mike, a hydraulic valve customer in the United States, came to me. He had been confused, since 2019, there have been continuous customer complaints about the hydraulic directional valve he purchased. All the complaints are that after the hydraulic directional valve has been used for a period of time, some hydraulic directional valves are deformed and some hydraulic directional valves are worn quickly.
Obviously, there is a problem with the heat treatment of the materials used in the hydraulic directional valve. Since 2019, due to the environmental protection policy, the domestic heat treatment plants have been vigorously rectified, and there are much fewer processing places. 50% of the hydraulic valve manufacturers do not have a place to do heat treatment to the raw materials. Even if heat treatment is done, 20% of the hydraulic valve manufacturers have to change the processing places for each external processing. I sent him several samples of AAK hydraulic directional valve and told him that the material hardness of our hydraulic directional valve has not changed, which always can reach about 50-55HRC or higher, and there is no problem with the special requirement of 65HRC. He didn't know that the service life of hydraulic valve is our hard index.
3 months ago, Mike issued a test order for the hydraulic directional valve. Each different part of the hydraulic directional valve is marked with different hardness requirements. He also wants to know how AAK ensures the service life of the hydraulic directional valve.

With 3 Tricks to Strengthen the Valve Spool, the service life of AAK Hydraulic Cartridge Directional Control Valve is twice that of its peers Blade is from Canada. He has been purchasing hydraulic components successfully for 3 years. Unexpectedly, a hydraulic cartridge directional control valve stumped him. In the second half of last year, a batch of their hydraulic logistics lifts were complained by customers, some of them were unable to work, probably because the hydraulic cartridge directional control valve leaked. After checking, it was found that the valve spool was deformed. The original manufacturer of the hydraulic cartridge directional control valves said that it had been shipped for 9 months, and some exceptions were inevitable. It is possible that the internal stress of the valve spool was not eliminated in time during the heat treatment process, resulting in deformation or cracking of the valve spool. However, there are more and more complaints later. Blade realized that the service life of the hydraulic cartridge directional control valves from the original cartridge valve manufacturer may be about 1 year. He had to find a new hydraulic cartridge directional control valve manufacturer with a service life of 2 years. A week has passed, and no one can guarantee a 2-year life span. Blade found AAK when browsing Google. He noticed that AAK was continuously supplying HydraForce, and left a message: Can AAK ensure that each hydraulic cartridge directional control valve spool is free of deformation or cracking within 2 years? I guess he encountered trouble in purchasing hydraulic cartridge directional control valves. After communication, I learned the above information. I replied that the life expectancy of 2 years should not be a big problem. Blade sent the drawing of the hydraulic cartridge directional control valve and asked for the lead time for 10 samples. After 45 days, AAK sent the samples of the hydraulic cartridge directional control valves, but there was no email from him after that. Last week, Blade suddenly sent an email, and it was a PO for 600 hydraulic cartridge directional control valves. It can be seen that the samples of AAK hydraulic cartridge directional control valve was approved by his customer. The valve spool is the key to long service life of this hydraulic cartridge directional control valve. 1. AAK select 20CrMo material to produce the valve spool. After quenching and tempering, the materials are more conducive to processing. Most hydraulic cartridge valve manufacturers ignore this action. 2. 0.25~0.35mm machining allowance shall be reserved for rough turning, then carburizing, quenching and high temperature tempering shall be carried out, and then the valve spool shall be subject to low temperature cold treatment. The surface hardness of such valve spool is above HRC63, and the residual austenite in the internal structure is eliminated.

Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
