AAK Multifunctional Hydraulic Cartridge Valve, benefit all 3 Parties

China [CN]

Monroe is from Sweden and has been purchasing hydraulic threaded cartridge valves from Ningbo for 3 years. In January of this year, their customer wanted to place a repeat order for one of their hydraulic unit equipment, but requested a 20% price reduction. Monroe wanted to reduce the price of the check valve, relief valve, and solenoid unloading valve in the hydraulic unit by 30% to meet customer requirement, but the original hydraulic threaded cartridge valve manufacturer cannot accept the new price.

Monroe contacted AAK for inquiry. When I saw his target price, I directly informed him that this price could not be achieved. Monroe did not give up and emailed me again. After communication, it was learned that his customer requested a 20% price reduction for the equipment. I felt a bit strange, but immediately realized that last November, AAK customized an integrated multi-function hydraulic threaded cartridge valve for a Spanish customer, replacing the 3 standard hydraulic threaded cartridge valves in their hydraulic systems. I suggested him sending me the schematic diagram of their equipment hydraulic system for a look. At first, he wasn't willing to do so, but when I sent him the customized case for this Spanish customer, he immediately compromised.

After discussion, AAK engineers found that Monroe's problem was similar to that Spanish customer. As long as the functions of the check valve, relief valve, and solenoid unloading valve in the equipment are integrated into a hydraulic threaded cartridge valve, not only can cost be reduced, but also the hydraulic oil circuit is more simplified. After 45 days, AAK sent 10 samples of hydraulic threaded cartridge valves.

Last week, Monroe emailed me that AAK hydraulic threaded cartridge valve was installed on their hydraulic unit, and the equipment functionality was not affected. He gave the customer a 30% discount, and the customer was surprised by the extra 10% discount and pleased to place the repeat order. Monroe told me that AAK multifunctional hydraulic threaded cartridge valve allows him to earn an additional 15% more in profits, his customer gets additional discounts, and AAK also has a new customer. I am happy to do things that benefit all 3 parties.

1. The hydraulic threaded cartridge valve sleeve is provided with a communication valve hole, a working port of the oil cylinder, a hydraulic control port of the oil tank, an oil inlet port, and an oil return port. A check valve spool is provided in the valve hole to control the on-off of the oil inlet and the working port for oil feeding or unloading. In this way, the one-way control function is realized, replacing the check valve of the original structure.

2. The hydraulic threaded cartridge valve is provided with an overflow valve spool, which connects the valve hole and the oil return port to provide a damping hole for unloading. At one end of the damping hole, there is an unloading valve spool that controls the opening and closing of the damping hole and the oil return port. The check valve spool is provided with a connecting channel that connects the valve hole and the working port for overflow or unloading. This achieves the unloading function, replacing the original structure of the solenoid unloading valve.

3. When the check valve spool is separated from the working port, the oil inlet port and the working port are connected to the unloading hydraulic control valve spool, and the connection between the valve hole and the overflow valve spool of the oil return port can also be disconnected. This achieves the overflow function and replaces the original structure of the relief valve.

AAK hydraulic threaded cartridge valve, 3 in 1 function, saving over 40% cost for customer, you can also try it!
