The opening and closing characteristics can reach 95% opening rate and 90% closing rate, the operating pressure swing is not greater than ± 0.1MPa, and the design service life is more than 1 million times. For this high precision, high stability and high durability 3-high hydraulic threaded cartridge valve, Jacob is surprised that the AAK hydraulic valve is successful in one-time sample, while most hydraulic valve manufacturers are not able to do at all.
Jacob is a purchaser of Intermot company in Italy. The company has a newly developed hydraulic motor, which needs to use hydraulic threaded cartridge valve. This motor is a high-frequency operation and has strict requirements for various parameters, especially for the parameters of hydraulic threaded cartridge valve, which has 3 high requirements of high accuracy, high stability and high durability. The boss asked Jacob to complete the procurement of this batch of hydraulic threaded cartridge valves within 60 days. He selected 4 from the original hydraulic valve suppliers to make samples. After installation, it was found that the opening and closing characteristics of hydraulic threaded cartridge valves can only reach 90% opening rate and 85% closing rate, which is 5% lower than the parameter requirements. Even the operating pressure swing of some hydraulic threaded cartridge valves exceeds 0.2MPa. In the last step testing, only 2 or 3 samples can be intact after 1 million durability tests. If all three requirements should be reached at the same time, nearly none of the samples meet the standard. Due to the limitation of equipment, the original manufacturer said it was difficult to improve significantly. Jacob learned about AAK hydraulic valve under the introduction of its peers. After browsing AAK website (www.aakindustry. com), he felt that the AAK hydraulic threaded cartridge valve might help him.
After receiving the parameter requirements and drawings of his hydraulic threaded cartridge valve, we found that the requirements of this hydraulic threaded cartridge valve are not simple, but our technical team needs to chew this hard bone and gave reply to Jacob that if it goes well, the samples of the hydraulic threaded cartridge valve can be sent within 20 days. On the contrary, it needs more time for proofing. Jacob hopes that AAK hydraulic threaded cartridge valve sample will be successful, which just meets the delivery time required by the boss. After 15 days, AAK sent the hydraulic threaded cartridge valve samples successfully. After installation and test by the engineer, all parameters of the hydraulic threaded cartridge valves are qualified and meet the 3 high requirements of high accuracy, high stability and high durability. After 25 days, the shipment of the hydraulic threaded cartridge valve was delivered as scheduled.
The boss knew a series of frustrations that Jacob encountered during this purchasing, and praised the 3 high standards of AAK hydraulic threaded cartridge valve, not only because the quality of AAK hydraulic valve is reliable, but also because of credit. Jacob wondered why AAK hydraulic valve can achieve a 3-high hydraulic threaded cartridge valve with only one-time sample, while most hydraulic valve manufacturers are helpless.
For the 3-high hydraulic threaded cartridge valve, AAK has Mikron GF machining center imported from Switzerland. It has advanced thermal stability, and the high precision is still stable in the long-time machining process. The Mikron GF unique spindle omnidirectional anti-collision protection technology (MSP) can prevent the spindle from collision failure, and integrate automatic solutions to ensure the stability of precision parts. There are also experienced technicians who have been in our factory for more than 10 years. Sometimes they can judge the production status by listening to the sound of the machine only, and each production link of the hydraulic threaded cartridge valve is engraved in their mind. The craftsman hand will produce good products, which is the strength of AAK. Integrity, sincerity, trust and credit are the way of hydraulic valves that AAK has always adhered to.
AAK hydraulic threaded cartridge valve, strength to speak, sincerity to do things, welcome a small try!
