Bront, from Israel, has been in contact with AAK for 3 years, but has not placed an order yet. During this period, there are inquiries about hydraulic cartridge valves, valve blocks and hydraulic manifolds. Although I marveled at the difficulty of doing business with this Israeli customer, I replied to his email in time. Sometimes, Surprise comes and catches you off guard. Bront placed a large order for 950 hydraulic flow control cartridge valves during the period of our CNY holiday.
I remember that this hydraulic flow control cartridge valve was inquired in May 2021. At the end of 2021, I was suddenly asked to provide 3 samples. This is the valve benchmarking HydraForce, and we have the stock. We sent the hydraulic flow control cartridge valves directly to him the next day, and then there was no further news from him, until this order was placed, which was more than 1 year from last contact. After communication, it was learned that he was fooled by 2 cartridge valve manufacturers in Ningbo 3 years ago, so he was very cautious about the cartridge valve manufacturers from Ningbo. It can be seen that not only the weak teammates hurt the mood, but also the weak peers hurt the order.
Bront told me that each parameter of AAK hydraulic flow control cartridge valve is benchmarking HydraForce, and its function also meets the requirements of their equipment. What worries him most is whether the performance can meet the requirements of the Israeli market. There is no repair in 1 year, no minor repair in 2 years, and no major repair in 3 years. Now 1 year has passed, and AAK hydraulic flow control cartridge valve is normal. It has proved that it has passed the threshold of "no repair in 1 year". Sometimes, without too much language, time is the best answer. I believe that this difficult Israeli customer has been settled by AAK. With our manufacturing quality, stable function and long performance, we impressed him. In the future, I will not worry about his order for cartridge valves.
AAK hydraulic flow control cartridge valve is benchmarking HydaForce, but the price is only 70% of HydraForce, or even lower. Compared with domestic peers, AAK hydraulic flow control cartridge valve may be 20% more expensive, but the service life is twice that of its peers. AAK hydraulic flow control cartridge valve, insists on 3 points: manufacturing quality, function and performance.
1. In terms of material selection, AAK adopts 20CrNi2MoV high carburized bearing steel imported from Germany, combined with carburizing pretreatment process, through secondary quenching + cryogenic treatment + low temperature tempering process, cooled to 650~700 ℃, and then discharged after cooling to 450~500 ℃. The microhardness of the treated material is 237~247 HV, and its wear resistance and contact fatigue properties are more than 3 times higher than that of the ordinary material.
2. The equipment is equipped with a precision honing machine imported from the United States. The accuracy of the hydraulic flow control cartridge valve hole is guaranteed. The accuracy of the IT7~4 level and the surface roughness can reach Ra0.32~0.04 μm. It is difficult to find 5 cartridge valve manufacturers like this in Ningbo.
3. In terms of inspection, AAK hydraulic flow control cartridge valve is 100% fully inspected. The self-developed high-pressure test bench and durability test equipment are used to check the pressure, flow and fatigue resistance of the cartridge valves.
AAK hydraulic flow control cartridge valve, 3 advantages, and its service life is twice that of its peers. You can also try it!
