Amador is from a hydraulic equipment company in Bolivia. Some time ago, he encountered problems with a hydraulic cartridge counterbalance valve. A logistics lifting device developed by his company needs to use hydraulic cartridge counterbalance valves. Amador selected a hydraulic cartridge valve manufacturer in Ningbo who has cooperated with him for 2 years to test samples. There was a hidden danger in equipment debugging: when materials rise to a certain height and stay, they will automatically fall down slightly and shake with low frequency. The reason is that the balancing capacity of the hydraulic cartridge counterbalance valve does not match the load. Although the hydraulic cartridge counterbalance valve has no leakage and no abnormal function, it must be optimized. The manufacturer had no idea for optimization and gave up. Amador contacted about more than 10 hydraulic cartridge valve manufacturers, but after a week, it was fruitless. Amistad became very worried.
When browsing Google, Amador found an AAK article about AAK unique designed hydraulic cartridge counterbalance valve helped Indian customer solve the hidden danger of hydraulic lifting device. This is very close to his current situation. He left us a message:
1. I paid attention to the personalized design of AAK hydraulic cartridge counterbalance valve, helping Indian customer solve the hidden danger of hydraulic lifting device.
2. Can AAK solve the hidden danger that the balance capacity of the hydraulic cartridge counterbalance valve does not match the load?
3. To customize a hydraulic cartridge counterbalance valve that the balance capacity matching the load, what is the lead time and cost?
I guess that he encountered trouble in purchasing hydraulic cartridge counterbalance valves. After communication, I learned the above story. According to the information provided by him, I told him that when the hydraulic cartridge counterbalance valve works, it mainly depends on generating a back pressure balanced with the load. When the load weight is small, the system will produce low-frequency jitter. When the load weight is large, it is easy to have a little leakage, causing the weight materials to fall slightly. This model has different problem from that Indian customer, and solution will be also different. Amador may have seen hope and requested AAK to try samples. After 35 days, AAK sent 12 hydraulic cartridge counterbalance valves.
3 weeks later, Amador informed us by email that with AAK hydraulic cartridge counterbalance valves installed, the equipment was debugged smoothly, and the load did not drop or shake. It will be promoted in the market soon, they are confident to get a large number of bookings.
1. For this hydraulic cartridge counterbalance valve, AAK adopts a cone valve structure and is equipped with a regulating rod, which can adjust the area of the initial orifice to match different flow ranges.
2. It is equipped with a load adaptation mechanism, a strong spring and a weak spring. The two springs are connected together through the spring seat. The weak spring in the low pressure section acts, the spring seat in the high pressure section automatically limits, and the strong spring acts.
3. The valve spool is flexible, controllable and free from load interference.
AAK hydraulic cartridge counterbalance valve, no hidden danger and safe, you can have a small try!
