Vadali is the purchasing manager of a hydraulic valve company in Russia. Some time ago, he wanted to purchase a hydraulic needle valve with the internal leakage parameters within 3 (drops)/ min@207bar. It took more than 10 days, but the needle valve samples provided by his hydraulic valve manufacturer failed to meet the test parameters. He did not know that AAK mass produced this type of hydraulic needle valves 3 years ago, so it is not difficult for us and our sample is approved 15 days after it was sent.
He contacted some hydraulic valve manufacturers from the Internet, because he never cooperated with them and was a little concerned. When hesitating, a buyer in his team suggested contacting AAK to have a try: AAK HYDRAULIC VALVE is a powerful manufacturer for hydraulic industry in Ningbo and is trustworthy. You can go to their website for a review and then decide whether it is worth a test with AAK Hydraulic Valve.
After reviewing our website www.aakindustry.com, Vadali posted a message on our website. After several rounds of interaction, he asked us to check his email after 2 hours. We were requested to spend 2 hours to research his hydraulic needle valve drawing carefully. Then he also wanted to communicate with our technical staff. It was the first time that we met a Russian customer that is so cautious. Maybe he had been in troubles for many times in the past with the other suppliers.
In the video conference, Vadali explained the requirements of every detail to the product in the drawing, and reminded the difficult points. At the same time, he repeatedly emphasized that the internal leakage parameters of the hydraulic needle valve must meet the standard of 3 (drops)/ min@207bar. We asked him what scene the hydraulic needle valve would be used in. When he learned that we shipped several shipments of similar hydraulic needle valves to Italy in 2018, he seemed to relax instantly and ended the meeting with a sentence "I'll be waiting for your approval sample for this needle valve. "
15 days after the samples were sent, we received email from Vadali that our hydraulic needle valve samples met the standard of 3 (drops)/ min@207bar, and the overall quality of AAK hydraulic needle valve is also satisfying. He was curious how we achieved it?
The internal leakage of hydraulic valves has always been the important index of AAK quality control. According to different scenarios of hydraulic valves, the sealing ring with higher anti-aging and stronger corrosion resistance is selected. In addition, inductance measuring instrument is installed on every lathe, grinder and other equipment to make sure that each part is in accurate size, then the machining accuracy of hydraulic valve is guaranteed.
Why does AAK hydraulic needle valve is better than its peers?
1. The core raw materials of AAK Hydraulic Valve are 100% imported, and advanced Swiss CNC lathes are equipped. The accuracy of AAK hydraulic valve is 30% higher than its peers.
2. AAK is able to produce high-precision hydraulic valves used in "aircraft", most of our peers can not think about it and are also not able to do it.
3. At present, AAK has 3 domestic design patents, 4 proprietary processing technologies and processes, and 80% of our peers can only produce conventional hydraulic valves.
No need to have any worry about the internal leakage of hydraulic needle valve produced by AAK, welcome to try an order!
