Hydraulic Relief Valves Resistant To 450bar High Pressure - China
price: 99.00 Dollar US$
High pressure hydraulic relief valve that can not be made by peers, AAK solved it with 68HRC material Logan, a British customer, checked with 10 hydraulic valve manufacturers that he often contacted, none of them can make a hydraulic relief valve with high pressure resistance of 450Bar.
Only AAK solved the problem of high pressure resistance with 68HRC material and ensured the performance of 2 million times.
According to the requirements of the engineer, Logan defines the material hardness of the hydraulic relief valve as above 68HRC, which is 10% higher than that of the conventional hydraulic relief valves.
After a round of consultation, 8 hydraulic valve manufacturers gave up, and the other 2 old hydraulic relief valve suppliers tried to make samples.
2 weeks later, the hardness of the samples of the 2 hydraulic relief valve suppliers remained at 63-65HRC, which was their maximum capability.
Logan had no choice but to look for the manufacturer of hydraulic relief valves again.
Logan consulted 20 companies online, and they all said that they were not confident to try 68HRC materials and 450Bar high-pressure hydraulic relief valves.
Logan was in a big headache.
Logan found some articles of AAK about the 450Bar high-pressure hydraulic valves on the B2B website, including 68HRC materials.
He emailed the drawing of hydraulic relief valve directly to AAK and asked AAK for samples.
After communication, we learned that the sample of this hydraulic relief valve was stuck on the material hardness.
I told him that 68HRC material was a must for the hydraulic relief valves with high pressure resistance of 450Bar, otherwise the service life of 2 million times could not be guaranteed.
AAK can send the hydraulic relief valve samples in 2 weeks, but the development cost of US$1, 200 for the trial order needs to be paid first.
Logan seemed to have concerns.
I said with a smile that AAK publishes articles on solving the difficult problems of hydraulic valves on the Internet every day.
If it's only for your $1, 200, our time is not worth it.
Logan was instantly relieved and informed the financial department of the payment.
He was surprised that the manufacturers he contacted could not make the high-pressure hydraulic relief valves, and AAK had solved the 68HRC material very early.
AAK has 3 points to ensure that the material can reach 68HRC, which is also the reason why most hydraulic valve manufacturers are uncertain.
1, The imported alloy billet is selected to replace carbon steel, and then the billet is forged at high temperature, and the hardness of the material is increased by at least 3-5%.
2, Quenching and tempering heat treatment shall be conducted after forging: 2 high-temperature normalizing + 2 high-temperature tempering shall be adopted, and each time the insulation shall not be less than 15 minutes.
There are tips for controlling the temperature range.
3, After tempering treatment, the workpiece is cooled to room temperature by combining water cooling and air cooling.
Firstly, the workpiece is water cooled to 475-485°C at a cooling rate of 8-9°C/s, then air cooled to 325-345°C, then water cooled to 195-2050°C at a cooling rate of 4-5°C/s, and then air cooled to room temperature.
In this 4-step process, most hydraulic relief valve manufacturers only take 2 steps.
2 weeks later, the hydraulic relief valve samples of AAK were sent out.
Logan told me 1 week after receiving the samples that AAK hydraulic relief valve was not only resistant to high pressure, but also the material hardness of each part reached the standard.
