Import Cartridge Check Valves Of High Quality — Buy in wholesale FOB from Supplier in China

Buy hydraulic cartridge check valve samples 3 times a year, and hit AAK with a big order for the fourth time 1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve website: Is there a hydraulic cartridge check valve equivalent to HydraForce? Ferdinan bought two hydraulic cartridge check valve samples from the model number I provided, then there was no news. Three months later, he bought another two samples of hydraulic cartridge check valves equivalent to SUN. Six months later, he sent a customized hydraulic cartridge check valve drawing and brought 6 samples, there was no email for 6 months. I think it's a bit abnormal, but if something is abnormal, there must be evil. He bought hydraulic cartridge check valve samples from AAK 3 times a year to test my patience and inspect the manufacturing quality of AAK. I can only comfort myself in this way. Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of hydraulic cartridge check valve customized last time. I knew that AAK had passed the investigation period of German customers. After communication, I learned that the hydraulic cartridge check valves that he purchased in Ningbo 2 years ago, were tested with 6 hydraulic valve manufacturers before and after. Either the first sample was OK, but the second one was not up to standard; Either the existing valve was tested OK, but the customized valve was abnormal. Time was wasted and delayed their equipment development. It turns out that Ferdinand was feared by some hydraulic valve manufacturers, so he was prudent to select new hydraulic valve manufacturers. This time, they will develop a hydraulic boarding bridge, which requires non-standard hydraulic cartridge check valves. From trial order to large order, AAK has been investigated for more than 1 year. Ferdinand said that the manufacturing quality of AAK hydraulic valves, whether the ones benchmarking international brands or non-standard customized ones, had been recognized by their engineers for their functions and performance, so they decided to place large quantity order of hydraulic cartridge check valves. The reason why AAK hydraulic cartridge check valve is different from other hydraulic valve manufacturers in Ningbo is that we insist on the quality of manufacturing. 1. Not make do with the equipment. No matter CNC machining center or machine tool, only high-precision ones are selected. At the same time, the fixture is upgraded and modified by ourselves, eliminating human error. 2. Materials should be paid attention to. Different kinds of imported high carburized bearing steel should be combined with AAK's proprietary heat treatment process. The hardness of the material has gone up several steps, and its wear resistance has been improved by more than 3 times. The thermal stability and compressive strength of materials have been far ahead of other hydraulic valve manufacturers.
