AAK Hydraulic Directional Control Valve No Leakage Seal Knack

Laird is from Brazil, and we met 2 years ago. He conducted 6 inquiries, 3 trial orders, and 1 trial order for hydraulic directional control valves with AAK. But there has been no inquiry in the past 6 months, which surprised me. I have checked with him twice but there has been no response. It wasn't until Laird contacted me a few days ago that I learned about the sealing story of the hydraulic directional control valve cover cap and valve cage.

In the second half of last year, their hydraulic power unit required hydraulic directional control valves. Laird inquired from 3 hydraulic directional control valve manufacturers in China, and AAK also provided quote. Laird chose a hydraulic directional control valve manufacturer with competitive price. 6 months later, the customer complained about hydraulic directional control valve leakage, causing unstable system operation.
