Description
After being used for a period of time, the hydraulic flow valve will scream, which is a common problem in the domestic hydraulic valve industry, also a pain point. Has this pain point been solved? It's solved. Who solved it? AAK Hydraulic Valve. The roundness error of sealing oil surface of AAK hydraulic flow valve is twice as small as that of its peers, Russian client can't refuse and have to choose AAK hydraulic flow valve.
 
In recent years, many manufacturers have been fighting a price war for survival. For hydraulic flow valves with the same price, there are problems such as valve stuck, oil leakage and even scream in the process of use. These problems do not happen to flow valves from only 1 or 2 manufacturers, but almost a common phenomenon in the hydraulic valve industry.
 
In April this year, we received an inquiry from a Russian customer about the hydraulic flow valve. From the customs data, we knew that this customer has been purchasing hydraulic flow valves from China for more than 4 years. We did not quote in a hurry. After several rounds of email communication, we finally knew why he wants to find a new supplier.
 
The hydraulic valves he purchased in the past, after being used for a period of time, there would be a scream. Although the previous supplier was very cooperative to improve, the scream of the hydraulic flow valve still exists, just that the probability of a scream to happen is reduced. Due to technique limitation, the problem can not be solved completely, he has to source another manufacturer who can produce the hydraulic flow valve and the hydraulic flow valve will not scream in the use.
 
He contacted with over 10 hydraulic valve manufacturers in different areas of China. After several rounds of communication, he selected 5 factories to have a second comparison. AAK Hydraulic Valve and the other 4 factories received the same drawing for a hydraulic flow valve, and were requested to offer samples and quotes for this hydraulic flow valve in 15 days.
 
AAK sent quotes and samples of the hydraulic flow valve in the requested time frame, and also reminded the customer that the main reason for the scream of the hydraulic flow valve is the roundness error of the sealing oil surface of the hydraulic valve.
 
If the size error of the sealing surface is too large, the force of the pressure regulating spring will be unbalanced, and the oscillation of the poppet valve will be intensified, resulting in scream phenomenon. The smaller the error size, the better. In the detection of hydraulic valve parameters, this size can be measured pertinently.
 
A month later, we didn't hear any news from this customer. We thought we were out from the competition. Last week, we received his inquiry unexpectedly. At the same time, he also told us the result of the comparison among the 5 hydraulic valve factories in the second round. He was very satisfied with the regular parameters of the hydraulic flow valves from all 5 factories. In the aspect of roundness error of sealing oil surface, the size error of 2 factories was 0.005-0.01mm, and 0.011-0.02mm from the other 3 factories. AAK hydraulic flow valve is one of those 2 factories. The reason why he finally chose AAK for cooperation lies in our kind reminder before sending samples. He saw our wholehearted treatment to him herein.
 
Why does AAK hydraulic flow valve is better than its peers?
 
1) AAK is equipped with honing machine imported from the United States and the inductance measuring instrument. The accuracy error of inner hole is controlled within +/-1 μm, the accuracy is guaranteed.
 
2) Core components, 100% imported materials; Each material, 100% testing, 100% heat treatment.
 
3) No re-buy means a failure for us. AAK adhere to sincerity to customers, adhere to mindfulness to quality.
 
AAK is a factory which is addicted to quality, facing the global hydraulic valve market, keeping pace with the international first-line brands, accurately controlling the error range and ensuring product quality.
