The Performance Of Aak Hydraulic Cartridge Relief Valve Is Twice Than Its Peers - China
price: 100.00 Dollar US$
Pancrazio is from a hydraulic equipment company in Italy.
In recent years, his purchase of hydraulic valves in China has been smooth.
Recently, he was trapped by a 450bar high pressure hydraulic cartridge relief valve.
At the beginning of last year, their new hydraulic power unit was complained by customers about unstable pressure supply 6 months after it was sold.
During after sales checking, it was found that the hydraulic cartridge relief valve spool was not flexible.
The original manufacturer of the hydraulic cartridge relief valve advised that under 450bar high pressure frequency use, the valve cage was deformed, then the valve spool was not flexible, the only solution is to replace the valves with new ones.
Later, with more and more complaints, Pancrazio realized that the service life of the hydraulic cartridge relief valves produced by the original manufacturer was only 6-9 months.
Such frequent replacement is not affordable, they must find a new hydraulic valve manufacturer, the service life of the hydraulic cartridge relief valve must be more than 24 months.
Pancrazio contacted more than 10 manufacturers, but none of them was able to guarantee that the service life of the hydraulic cartridge relief valve under 450bar high pressure, can be 2 years.
2 weeks passed, but no progress.
Pancrazio became panicky.
Pancrazio saw in Google that AAK released a series of 450bar pressure resistant hydraulic cartridge valves and left a message asking: How long is the service life of AAK's 450bar pressure resistant hydraulic cartridge relief valve? There are similar messages every day.
I only answered "The price of AAK hydraulic cartridge relief valve is 20% higher, but its service life is twice that of the peers".
In the afternoon of the same day, I received the drawings of the hydraulic cartridge relief valve and the pictures of the original manufacturer's hydraulic cartridge relief valves from Pancrazio.
He emphasized the requirements of the 450bar pressure resistance and the service life of 2 years.
Our engineer is a little surprised that the original manufacturer's hydraulic relief valves will be abnormal in 6 months.
After a careful look at the design of the original hydraulic cartridge relief valve, we had an idea and suggested making samples directly.
Although Pancrazio was some hesitant, there was no better choice.
After 45 days, AAK sent 50 hydraulic cartridge relief valves to replace the ones on those abnormal equipments.
Last week, Pancrazio emailed us that AAK hydraulic cartridge relief valves have been installed in the equipment for 1 year, there was any complaint about unstable pressure supply.
Their engineers realized that AAK had directly modified the design of the original hydraulic cartridge relief valve, and they admired our minds.
I told him that if there was no accident, in 24 months, there would be no repair report for AAK hydraulic cartridge relief valve and no complaint from the customers.
This hydraulic cartridge relief valve, hydraulic system and working conditions are a little special.
The original hydraulic cartridge relief valve is designed to be composed of a valve cover, a valve cage and a valve spool.
Most hydraulic valve manufacturers mainly focus on standard parts and can only produce according to drawings, without system knowledge of hydraulic valves.
We operate like this, which is the 3 points admired by their engineers.
1 - We open a large round hole in the center of the upper part of the valve cover, and the valve spool reaches the valve cage through the large round hole and is installed in the inner cavity of the valve cage.
This is the change of the appearance.
2 - Enlarge the valve spool diameter and valve cage inner diameter in the same proportion, increase the valve spool stroke, increase the oil flow, and make the system oil more stable, which is helpful to the performance.
3 - The area around the oil outlet of the valve cage is designed to be convex, and the high-pressure oil flows out through the outlet of the valve cage, which has a buffer, which is more resistant to high pressure and has better performance.
The price of AAK hydraulic cartridge relief valve is 20% more expensive, but its service life is twice that of its peers.
