Cartridge Needle Valve Safe For 18 Months In The Desert - China

price: 60.00 Dollar US$

AAK Hydraulic Cartridge Needle Valve is durable for 18 months in the desert, and the one from original manufacturer will not work in 9 months Castel is from Saudi Arabia, and their company mainly sells oil mining machinery.

At the beginning of last year, one of their hydraulic platforms was complained, and the equipment went on strike 8 - 9 months later.

After checking, it was found that the shoulder and pin hole of the hydraulic cartridge needle valve spool in the system were broken.

The hydraulic cartridge needle valve manufacturer advised that the same model of hydraulic cartridge needle valve was supplied to the South American market.

Within 1 year, there was no complaint.

The manufacturer explained that the brittle fracture of the hydraulic cartridge needle valve spool was caused by the working conditions and working scenarios.

The boss was not satisfied with the manufacturer's buck passing, and asked Castel to found a manufacturer whose hydraulic cartridge needle valve can be used for more than 1 year.

Based on the requirement of "hydraulic cartridge needle valve can be used in desert with a service life of more than 1 year", Castel started to look for new cartridge valve manufacturers.

After 1 week, there was no result.

Castel was a little flustered.

Castel noticed the article published by AAK in B2B that "AAK hydraulic counterbalance valves have been used in Sandstorm for 12 months, was free of corrosion”, he emailed us to ask if AAK can customize the hydraulic cartridge needle valves used in desert with a service life of more than 1 year.

After communication, we learned that he had trouble in purchasing hydraulic cartridge needle valves.

The durability of the hydraulic cartridge needle valve is related to the material, but the structure can not be ignored, especially for the complex working conditions, it should be designed specifically.

Castel may have seen hope, and asked AAK to make 20 samples of hydraulic cartridge needle valves.

After 45 days, AAK delivered the trial order.

After the hydraulic cartridge needle valves were sent out for 2 months, there was no information from Castel.

I followed up curiously, and he said that the boss would not reply until 1 year later, then there was no information anymore.

I almost forgot about Castel.

Until last week, he emailed us an order for 600 hydraulic cartridge needle valves, and specially emphasized that the second batch of hydraulic cartridge needle valves should be of the same quality as the trial order, not the best, but should not fluctuate.

I agree with that.

It's not the best quality, but the stable quality with few failures.

Some small faults can be solved as soon as possible, but they are very troublesome if happen again and again.

The quality should be reliable, and will not require repair for a year or even longer.

Castel said that AAK hydraulic cartridge needle valves can be used for 18 months.

Although the price is a little more expensive than the original hydraulic cartridge valve manufacturer, the service life is twice that of the original manufacturer.

The sticking point of AAK hydraulic valve is the stability of function and reliability of performance.

This hydraulic cartridge needle valve focuses on 3 points: 1 - The shoulder of the hydraulic cartridge needle valve spool is increased to the circular radius, which effectively reduces the shoulder stress of the spool and improves the service life of the spool.

2 - The pin hole setting is optimized to reduce the alternating influence of the load change on the valve spool stress.

3 - The cantilever beam of the wedge structure of the hydraulic cartridge needle valve is changed into a simply supported beam, which increases the stability of the valve spool and can play an anti vibration role to a certain extent.

AAK hydraulic cartridge needle valve, safe for 18 months, you can also have a small try! AAK HYDRAULIC CARTRIDGE VALVES (414) 2022-11-18
