Directional Control Cartridge Valve 3 Optimizations 2 Benefits - China

price: 60.00 Dollar US$

AAK Hydraulic Directional Control Cartridge Valve is optimized in 3 ways, which gives Eugenia 2 major benefits Eugenia is from Belarus and has purchased hydraulic cartridge valves from AAK for 3 years.

In the second half of last year, they developed a hydraulic power unit.

Their customer asked for a price reduction of 15% to meet the market demand.

Eugenia required the original hydraulic directional control cartridge valve manufacturer and his hydraulic component suppliers to reduce the price simultaneously, but it did not meet 15%.

The boss was unhappy.

Eugenia was very upset.

Eugenia contacted me.

As soon as I heard about the price reduction request of the hydraulic directional control cartridge valve, I gave up directly.

7 days later, Eugenia came to me again and asked if we could reduce the hydraulic components and combine them into a new hydraulic unit.

This aroused my interest.

According to the schematic diagram of the hydraulic system provided by Eugenia, AAK engineers found that there are multiple directional control cartridge valves in the equipment, which not only makes the flow path complex, but also increases the cost.

Is it possible to optimize the hydraulic directional control cartridge valve in the system to replace the function of the multiple valves, and reduce the cost? Eugenia requested AAK to try samples.

After 45 days, AAK sent 12 samples of hydraulic directional control cartridge valves.

2 weeks later, Eugenia informed us that after replacing those hydraulic components with AAK hydraulic directional control cartridge valve, the function of the hydraulic unit was not affected.

AAK hydraulic directional control cartridge valve controls the flow of the oil port through the opening size of the hydraulic control oil port, simplifies the hydraulic oil circuit, reduces energy consumption by a little, and reduces the overall procurement cost by 20-25%.

The use of AAK hydraulic directional control cartridge valve brings her 2 additional benefits.

Can Eugenia be unhappy? 1 - In the valve body of the hydraulic directional control cartridge valve, there are left and right through valve holes and are connected with the valve spool in a sliding way.

On the side of the valve body, there are 3 annular grooves from left to right.

Each annular groove has an oil inlet connected with the valve hole and a flow hole.

The screw sleeve is installed at the left end of the valve body and is connected with the transmission rod at the left end of the valve element.

2 - There is a screw plug at the left end of the hydraulic directional control cartridge valve hole, which is sleeved on the transmission rod, and the return spring is sleeved on the outside of the transmission rod.

There is a first spring seat on the transmission rod, and its right end extends into the valve hole through the screw plug.

When the valve spool moves to the left, the return spring is compressed through the first spring seat.
