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, 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. On site, it was found that the leakage point was between the hydraulic directional control valve cover and valve cage. The original valve manufacturer claimed that it was caused by severe vibration and he could only guarantee the service life of the hydraulic directional control valve for 6 months. However, the customer requested at least 1 year or more.

 

Laird thought of the hydraulic directional control valve previously supplied by AAK, which had no abnormal leakage and had a service life of over 1 year. I told him that last time, AAK hydraulic directional control valve was quoted 20% expensive than its peers, but its service life was twice that of its peers. This time, it has been verified again with you. Let's make a comparison. Our quotation for this hydraulic directional control valve is $12.00. Based on a 1 year calculation, the monthly usage cost is $1.00. If the original valve manufacturer's price is $10.00 and the service life is 6 months, then the monthly usage cost is over $1.50. This is the invisible benefit that AAK hydraulic directional valve brings to customers. Laird agreed with my explanation and sent an order for 200 pcs of hydraulic directional valves the next day.

 

How to avoid vibration and leakage in the sealing between the AAK hydraulic directional valve cover and valve cage? This is a small detail, AAK has tricks. AAK uses thread anaerobic adhesive, which is evenly injected into the joint and self cured at room temperature. After curing, it will not be corroded by hydraulic oil or other organic media, and the key lies in the uniform injection method. This avoids loosening of threads caused by vibration between the hydraulic directional valve cover cap and valve cage, while protecting the joint from corrosion. The seal between the AAK hydraulic directional valve cap and valve cage is not loose or leaking.

 

AAK hydraulic directional valve, no leakage, you can also give it a try!
