Hydraulic Cartridge Counterbalance Valve 3 Highlights - China

3 Highlights of AAK Hydraulic Cartridge Counterbalance Valve, Camden gave up SUN Camden is from a hydraulic equipment company in Sweden and has been engaged in procurement for 2 years.

One of their customers ordered 2 sets of customized hydraulic power units, and specially reminded that the working environment of the equipment is 20 ℃ below zero.

The hydraulic power unit is required to be durable for at least 1 year, and its stability should be the first.

Their engineer suggested purchasing SUN hydraulic cartridge counterbalance valves, but the parameters of SUN standard parts could not fully meet the requirements of equipment working conditions, and there is no enough quantity and time to customize SUN hydraulic cartridge counterbalance valves.

Camden contacted a local manufacturer of hydraulic cartridge counterbalance valves, and the manufacturer was willing and confident to sample.

3 months later, the customer complained that the equipment was not stable enough, but it was barely usable.

6 months later, the equipment went on strike.

During after sales service checking, it was found that the control of the hydraulic cartridge counterbalance valve was abnormal.

The original manufacturer was surprised and confused.

After disassembling the hydraulic cartridge counterbalance valve, it was found that the installation torque was too large, which could easily cause the valve to jam, and there were also abnormal seals, the original manufacturer had to surrender.

Camden tried to find a new manufacturer of hydraulic cartridge counterbalance valve.

After a week, it was fruitless.

The boss blamed Camden for poor procurement.

Camden noticed AAK at Google and found that AAK Hydraulic Valve is SUN's supplier of hydraulic components for 5 consecutive years.

He left a message: SUN is unwilling to sample a hydraulic cartridge counterbalance valve, and AAK is able to do a good job? The hydraulic cartridge counterbalance valve shall be durable for not less than 1 year, and its stability shall be guaranteed.

I have judged that he is in trouble when purchasing hydraulic cartridge counterbalance valves.

According to the hydraulic schematic diagram of the system, hydraulic cartridge counterbalance valve drawings, equipment working condition parameters and working scenarios provided by Camden, AAK engineer found that this hydraulic cartridge counterbalance valve is similar to the hydraulic cartridge relief valves that we supplied to a Russian customer 1 year ago, which had a service life of at least 1 year under extremely cold conditions of - 55 ℃.

Camden was very happy to learn about the similar customer case of AAK, and requested to customize the hydraulic cartridge counterbalance valve and benchmark SUN.

I said that AAK does not pursue whether this hydraulic cartridge counterbalance valve is advanced, but it must benchmark SUN in stability and reliability.

At the same time, AAK needs to redesign this hydraulic cartridge counterbalance valve from 3 aspects.

After 45 days, AAK hydraulic cartridge counterbalance valve samples were sent.

3 months later, Camden emailed us that yesterday, the customer reported that the stability of the hydraulic power unit with new hydraulic cartridge counterbalance valve was much better than that of the last time.

If there was no abnormality within 1 year, the purchase of equipment would be increased.

I told him that the AAK hydraulic cartridge counterbalance valve, which has no worries for 1 year, has 3 main highlights: 1 - The installation torque of hydraulic cartridge counterbalance valve designed by peer is too large, which will affect the valve spool and control piston, causing valve jamming.

The hydraulic cartridge counterbalance valve designed by AAK, the inserts form a snap floating connection with the valve body, and a seal connection with the valve cage to avoid jamming.

2 - AAK sets a throttling slot between the pilot valve spool and the main valve spool, to achieve stable control pressure at the pilot port, with mild changes in the opening phase.

During the control load drop, the main valve spool opening is not affected by the load pressure.

3 - AAK makes the outer diameter of the pilot mechanism of the hydraulic cartridge counterbalance valve into a ladder shape, avoiding possible leakage caused by cutting of the seal ring, and increasing the service life by at least 20%.

AAK hydraulic cartridge counterbalance valve, 3 highlights, no worry in at least 1 year of use, you can also have a small try! AAK HYDRAULIC CARTRIDGE VALVES (400) 2022-11-04
