The Hydraulic Relief Valve is Flexible without Jamming. Nick, who has cooperated for 6 Years, Still orders back from AAK

AAK hydraulic pilot operated relief valve adopts diamond reamer technology, and the valve hole accuracy of hydraulic relief valve is guaranteed to be within 3μm, the surface roughness reaches Ra0.2-0.4. AAK hydraulic relief valve is sensitive and the valve spool is not stuck. It exceeds 99% of its peers. Nick, who has cooperated for 6 years, still orders back from AAK.

Nick is the buyer of John Deere company. He has cooperated with AAK hydraulic valve for more than 6 years. The boss trusts him very much. Recently, a batch of bulldozers they sold to South Africa were complained that the hydraulic system was unable to start. The problem was that the valve body hole roundness of the hydraulic pilot operated relief valve was poor and the valve spool was easy to get stuck. The boss felt very strange. In the past 6 years of cooperation with AAK hydraulic valve, there was no complaint about the hydraulic pilot operated relief valve. After checking, he knew that Nick found a new supplier for this hydraulic pilot operated relief valve, which is 17% cheaper than AAK. The approval samples of hydraulic relief valve provided by the hydraulic valve manufacturer are qualified. Unexpectedly, the accuracy of hydraulic relief valve shipment is uneven. The boss asked Nick to contact AAK hydraulic valve, reproduce the hydraulic relief valves, and ship them directly to South Africa.

We were a little surprised when we received an email from Nick to purchase 100 hydraulic relief valves and ship them directly to South Africa. Nick frankly told us that there were problems with the shipments from the original hydraulic relief valve manufacturer and needed the help of AAK to solve the customer complaints together. The difficulty of customer is the difficulty of AAK. We give priority to the production of this batch of hydraulic relief valves. After 35 days, the South African customer of Nick received the replacement of hydraulic pilot operated relief valves, and the whole after-sales process satisfied the customer.

Nick sent an inquiry for a new hydraulic relief valve a few days ago. He specially said that his boss asked him to take AAK as the first choice for future hydraulic relief valves, because the quality of AAK hydraulic relief valve has not had any quality complaints in the past 6 years. Comparing the hydraulic relief valves produced by AAK with its peers, it will show why AAK hydraulic relief valve is sensitive and the valve spool is not stuck, which exceeds 99% of its peers. Nick, who has cooperated for 6 years, still orders back from AAK.

For the machining of hydraulic relief valve hole, most peers use rigid Boring Reamer or stepped reamer, which has high production efficiency, but the hole accuracy is generally 7μm or above, it is difficult to stabilize on one data, and the roughness is fluctuated at the range of Ra1.6-3.2. AAK uses the diamond reamer to process the valve hole of hydraulic relief valve. In the grinding process, the reamer moves regularly in circumference and axis, and the metal is cut completely without trace with the micro edge of diamond particles. The accuracy of the valve hole of the hydraulic relief valve is guaranteed to be within 3μm, the surface roughness reaches Ra0.2-0.4, which almost avoids the roundness and cylindricity errors of the valve hole, improves the coaxial accuracy, and unifies the accuracy data. AAK hydraulic relief valve is sensitive, and the valve spool is not stuck, exceeding 99%.

The 17% more expensive AAK hydraulic relief valve, has its unique valve hole processing, incomparable quality. You are welcome to have a small try.
