Santiago is from Spain. He has been a purchaser of the company for 3 years. His boss trusts him very much. Unexpectedly, a hydraulic counterbalance valve overturned him. In the second half of last year, one of their hydraulic cylinders was complained by the customer because of shaking. The engineer judged that the hydraulic counterbalance valve used was abnormal, but the reason was unknown. After receiving the defective hydraulic counterbalance valve, the original manufacturer found that the internal pressure spring had failed, resulting in the slow response of the hydraulic counterbalance valve. This is the best pressure spring of the original manufacturer, but it still could not withstand the impact of 450bar high pressure and high frequency. Santiago had to change the manufacturer of the hydraulic counterbalance valve. After more than a week, no manufacturer was able to guarantee that the valve would not fail under the high pressure of 450bar for more than 1 year. It had been nearly 2 weeks, and there was no solution to customer complaints. Santiago was under great pressure.

 

Santiago accidentally found AAK Hydraulic Valve in Google. He left a message on the AAK website asking whether the pressure spring of the hydraulic counterbalance valve would not fail for more than 1 year under the high pressure and high frequency working condition of 450bar? According to his drawings and working conditions, I told him that if the German HAWE was used, it would be 100% OK, but the quantity was too small, and HAWE would not necessarily accept it, and the cost was not low. AAK has a similar hydraulic counterbalance valve. Let's see if it can be a substitute first? 3 weeks later, Santiago informed that the AAK hydraulic counterbalance valve could be installed with their hydraulic cylinder and operated normally. But he seemed worried that it would not last long.

 

I told him that Germany HAWE is the first brand of hydraulic valves in the subdivision field of high pressure resistance. The function of AAK hydraulic counterbalance valve benchmarks HAWE, which has been shipped for many times. The fact has proved that there is no repair report for 1 year, and the pressure spring can not lose efficacy for more than 1 year. Why dare I say so? The pressure spring of AAK hydraulic counterbalance valve is made of 60Si2CrVA alloy steel. At the same time, in combination with special heat treatment process, 60Si2CrVA pressure spring steel is heated to 860 ° c, kept for 20-40 min for austenitizing, and then subjected to short-term high-temperature water cooling quenching to room temperature. The comprehensive properties of the treated 60Si2CrVA spring steel have been improved by at least 2 times, especially the strength and toughness of the pressure spring, which quality far exceeds most springs. Most hydraulic valve manufacturers of hydraulic counterbalance valves may be able to find good materials, but they cannot do well in heat treatment.

 

Yesterday, Santiago sent an inquiry for another high pressure resistant hydraulic counterbalance valve and told me that the last hydraulic counterbalance valve benchmarking HAWE had been used for almost 1 year, as promised by AAK, and there was no complaint, so his boss specially requested that AAK should be the first choice of the inquiry and sample for all high pressure resistant hydraulic valves. I know that AAK has conquered another high-quality customer by virtue of its manufacturing quality.

 

AAK hydraulic counterbalance valve, benchmarking HAWE, no failure for more than 1 year, you can also have a small trial!
