Maverick is from a Canadian hydraulic equipment manufacturing company. In the first half of last year, the high-temperature hydraulic power unit dedicated to meltblown equipment sold by their company for less than 4 months was complained by customers. The engineer found that the opening pressure of the hydraulic pilot operated relief valves on the equipment deviated from the set standard pressure, resulting in unstable pressure supply. Through further inspection, it was found that the pressure spring in the valve failed. According to the feedback from the original manufacturer of the hydraulic relief valves, the fatigue resistance of the pressure spring is reduced due to the working condition environment exceeding 350℃ and long-term full load operation, so the pressure spring can only be replaced. 3 months later, the same problem occurred again. The customer complained directly to the boss. The boss asked maverick to source the hydraulic pilot operated relief valves with a service life of more than 1 year to replace the current stock. Maverick contacted more than 10 hydraulic relief valve manufacturers and they all said that the pressure spring life of the hydraulic pilot operated relief valves can only be guaranteed for 6 months under the high temperature of 350℃. The boss has pushed twice, but the new manufacturer of the hydraulic relief valves has not been found. Maverick is worried.

Maverick found AAK Hydraulic Valves from Google and left us a message: how much temperature can the pressure spring of hydraulic relief valve withstand and ensure a life of 1 year? I answered directly: AAK used to ship hydraulic valves with high temperature resistance of 500℃, and no customer complained that the pressure spring was invalid. The next day, he provided the working condition requirements and production drawings of the hydraulic pilot operated relief valve, and informed that the current procurement of this hydraulic relief valve was not smooth, and urgent replenishment was needed to replace it. AAK engineer found that the hydraulic pilot operated relief valve not only has high requirements for the spring, but also has shortcomings in the design. We advised the design change suggestions and promised to complete the trial order within 45 days.

After 45 days, AAK sent out 30 hydraulic pilot operated relief valves. Last week, Maverick sent an e-mail that it is going to be 1 year, the equipment installed with AAK hydraulic pilot operated relief valves has no abnormal pressure supply till now. He needs to re-order 300 more.

Under high temperature conditions, the service life of AAK hydraulic pilot operated relief valve is more than 1 year, it is so different from the most of the peers are due to the following 3 points:

AAK engineers have more than 20 years of development and design experience. The dynamic balance of the valve spool of this hydraulic pilot operated relief valve is high. Only by optimizing the valve port size can the flow always be controlled within the set pressure range. On the contrary, it will affect the pressure supply. This skill is very particular.

AAK has unique method to choose pressure spring, chooses 30W4Cr2V heat-resistant pressure spring steel with the best opening ratio as the core component of this hydraulic pilot operated relief valve according to the pressure range and spring stiffness coefficient. The pressure spring will not fail even if the oil temperature is higher than 500℃.

AAK Hydraulic Valve has developed 500 non-standard customizedhydraulic cartridge valvesfor 7 world top 500 enterprises.

Maverick also privately informed that the performance of AAK hydraulic pilot operated relief valve was admired by their engineers and they introduced AAK to several peers.
