Caleb is the purchasing manager of Red and White Valve company in California. He is responsible for purchasing all the hydraulic valves from China. This time, he fell over the hydraulic system of the relief valve. Nearly 20% of the hydraulic relief valves purchased have no pressure in the hydraulic system during commissioning, then the customer have not been able to receive the full shipment due to shortage resulted from defective products.The general manager of import dept was angry and asked Caleb to meet the demand of this VIP customer within 3 weeks. However, the original hydraulic valve manufacturer is in lack of technology, and always get no accurate solution. For getting into this trouble, even the delicious Chinese dishes he has always liked are now dull.
There are several situations that lead to no pressure in the hydraulic system of the hydraulic relife valve:
1. The hydraulic relief valve is not cleaned during the assembly process, and there are foreign matters between the valve spool and the valve seat.
2. Due to low accuracy, the main valve spool is stuck.
As long as the accuracy of the valve spool and sleeve is guaranteed and attention is paid to the details in the assembly process, this phenomenon can be completely eliminated.
In the middle of January 2021, Caleb contacted us from the Internet. At that time, because our employees in the factory were busy on catching up delivery, they didn't notice his email that day. The next day, Caleb contacted us by landline. After a brief introduction and discussion, he hoped that our technical team would have an immediate conference call with him. After more than 2 hours of talking, he asked us to watch for his email, and then happily hung up. 10 minutes later, we received a hydraulic relief valve design drawing and a hydraulic relief valve stock sample picture from Caleb, he asked us to submit counter sample within 10 days. Soon, we sent samples of our hydraulic relief valve in 5 days. We also received the sample fee and express fee that he paid voluntarily.
Half a month later, we still didn't hear back from Caleb. We thought that he didn't plan to proceed with this order. Surprisingly, when we came back from Spring Festival and opened our email, we found that Caleb's order was already there during the Spring Festival. Later, we learned that he asked for more than one hydraulic manufacturers to send samples. Finally, through parameter comparison and for our proofing efficiency, he decided to cooperate with AAK without hesitation.
Yesterday, I interacted with Caleb on LinkedIn and learned that their VIP customer was very satisfied with the speed of their company to solve the problem. The general manager of import dept also praised him at the summary meeting in January and called on other managers to keep up with him.
Maverick is from a Canadian hydraulic equipment manufacturing company. In the first half of last year, the high-temperature hydraulic power unit dedicated to meltblown equipment sold by their company for less than 4 months was complained by customers.
At the beginning of this year, Liam from the Netherlands found AAK Hydraulic Valves on Google. He told me that he encountered the dilemma of purchasing hydraulic pressure reducing valves. Their company has developed a hydraulic support column used in coal mining.
The processing difficulty of hydraulic relief valves with deep hole is a pain point in the industry. The greater the length diameter ratio, the greater the difficulty. Pablo, an American Hydraulic customer, has recently been besieged by an order for hydraulic relief valves with a length diameter ratio of 11:1.
2 months ago, Jackson from the United States left a message on AAK website: I read the article "The throttling groove is changed from double to single triangle. The hydraulic counterbalance valve has no vibration. AAK makes Henry feel at ease for vacation".
