For Hydraulic Cartridge Directional Control Valve With no wear valve spool, the

Ibeamaka is from a hydraulic equipment company in Pakistan, and has been in the hydraulic industry for 3 years. At the beginning of last year, their hydraulic packer was complained by customers. The leakage of the hydraulic cartridge directional control valve in the system caused the equipment to work weakly, which was caused by the wear of the valve spool end. The original manufacturer of the hydraulic cartridge directional control valve said that because the system was opened and closed frequently, even if the valve spool of the bearing steel was worn, it was inevitable, so the service life of the hydraulic cartridge directional control valve could only be within 1 year. The boss was not satisfied with the original manufacturer's after-sales guarantee of more than 9 months, and requested to change the manufacturer, and the service life of the hydraulic cartridge direction control valve should not be less than 18 months. 1 week later, only one hydraulic cartridge valve manufacturer was willing to sample, which made Ibeamaka more worried.

Ibeamaka searched the website of AAK hydraulic valves on Google and noticed many customer cases about the service life of AAK hydraulic cartridge valves. He sent an email asking if AAK can customize the hydraulic cartridge direction control valve and the service life shall not be less than 18 months. According to his drawing of hydraulic cartridge directional control valve, he also specially reminded that the original manufacturer's problem on the valve spool. I told him that the hydraulic cartridge directional control valve spool of the original manufacturer was probably deformed after heat treatment, showing warping at both ends. During finishing, the end protective layer was removed, which affected the wear life of the valve spool. 5 years ago, AAK learned a similar lesson and has already upgraded the process. The valve spool is free of wear and has a service life of more than 18 months. Ibeamaka quickly sent an order for 120 hydraulic cartridge directional control valves.

Last week, Ibeamaka sent an email. The hydraulic packers that used AAK hydraulic cartridge direction control valves had been working for 18 months. There was no complaint about the leakage of the hydraulic cartridge directional control valves. The boss was very satisfied. AAK hydraulic cartridge directional control valve spool is wear-resistant and durable, and its service life is twice that of the original manufacturer. It is due to the optimization of the process and 3 tricks in the processing process:

1. The spool of the hydraulic cartridge directional control valve is provided with a longitudinal main body of several bosses and two end faces at intervals. The included angle between the transition surface between the end of the valve spool and the adjacent boss and the axial direction of the valve spool is 5 degrees. This processing is particular, and most hydraulic cartridge valve manufacturers cannot control the accuracy.
