AAK Hydraulic Flow Control Valve with 3 major advantages, recognized by Yagmur
Yagmur is from T�¼rkiye and mainly purchases hydraulic cartridge valve standard parts from Ningbo. Recently, they developed a hydraulic drilling equipment that uses hydraulic flow control valves that are modeled after HydraForce standard parts, and purchased from a hydraulic valve manufacturer in Ningbo. During equipment debugging, it was found that the flow rate of the hydraulic flow control valve was unstable, and the leakage rate did not match the hydraulic system. The original hydraulic flow control valve manufacturer stated that this is a replica of HydraForce and is unwilling to optimize its function for several hydraulic flow control valve samples. Yagmur checked with several other hydraulic valve manufacturers, but they were not interested. Yamour was very anxious.
The original hydraulic flow control valve manufacturer introduced AAK to Yagmur. After communication, it was learned that her requirements for this model include low leakage and high precision requirements for valve holes. Based on the hydraulic system schematic provided by her and the industry model code of the HydraForce hydraulic flow control valve, I recommended a ready-made sample to her. As long as the external dimensions meet his manifold requirements, it can solve the problem she is currently facing.
2 weeks after the sample was sent out, Yagmur informed via email that the drilling equipment was successfully debugged. The low leakage of AAK hydraulic flow control valve meets their system requirements, especially the flow control function that they are very satisfied with. I told her that for this AAK hydraulic flow control valve, we have 3 major advantages:
1. The internal leakage of AAK hydraulic flow control valve is 5 drops/min, while most peers can only achieve 8-10 drops/min.
2. The hole accuracy of AAK hydraulic flow control valve can reach IT6-IT7 level, and the surface roughness can reach Ra0.2-0.025m.
3. The AAK hydraulic flow control valve function fully aligns with the standard parts of HydraForce, and there are probably no more than 3 manufacturers in Ningbo to meet it.
The vast majority of hydraulic flow control valve manufacturers in the industry do not use forming cutters for machining small quantities of hydraulic flow control valves, but use CNC instead to process according to dimensional requirements. The result of this machining is an accuracy of 0.03mm and a positional tolerance of 0.02mm. The AAK hydraulic flow control valve is processed with forming tools, and the dimensional accuracy of the valve hole after processing reaches 0.01mm, with a positional tolerance within 0.007mm. At the same time, AAK has its own standards for tool selection, with hardness of HRA90 alloy material, heat resistance of 900 , valve hole accuracy of IT6-IT7 level, surface roughness of Ra0.2-0.02m, and tool life is 30 times higher than ordinary alloy steel.
