Cartridge Relief Valve Meeting 3 High Requirements - China

For the Cartridge Relief Valve with 3 requirements, AAK got a big order 3 months later The local Israeli manufacturer was not willing to take risk to develop the hydraulic cartridge relief valve due to small size, and gave it up.

After taking over, AAK made 3 improvements in the structure, met the 3 requirements: 450bar high pressure resistance, 500L/min large flow, low pressure loss, and small volume.

3 months later, Vaughan sent an order for 600 cartridge relief valves.

Vaughan is from Israel, and they mainly focus on hydraulic equipment in the military market.

At the beginning of last year, they customized a hydraulic power unit, which needs to have a pressure resistance of 450bar, the flow controlled by the cartridge relief valve in the system exceeds 500L/min, with low pressure loss and small volume.

He contacted a local manufacturer to try the sample.

The manufacturer reported that there was no problem with the functional requirements, but the size was too small and the risk was high, so he was unwilling to develop it.

Vaughan contacted more than 10 cartridge valve manufacturers, but it was fruitless after 1 week.

Vaughan noticed AAK's article on high pressure and large flow cartridge valves on B2B.

He emailed me: can AAK try the cartridge relief valve with high pressure resistance of 450 bar, flow over 500L/min, low pressure loss and small volume? My reply: It depends on how small the volume is.

Vaughan sent the drawing.

After getting the confirmation that AAK can optimize the internal structure of, he confirmed for us to make samples.

After 50 days, AAK sent 12 cartridge relief valve samples.

3 months later, Vaughan sent an order for 600 cartridge relief valves.

Their engineers were very satisfied with AAK samples, which not only met the high pressure resistance of 450bar, large flow of 500L/min, low pressure loss, and small volume, but also completely met the requirements of the drawing, solving the space barrier of their power unit.

AAK has made 3 improvements in the structure: 1 - The inner wall of the outer end of the hydraulic cartridge relief valve cage is provided with a boss to limit the spool in the cage.

The spool, the cage and the cover form the first chamber.

The first chamber is provided with a pressure regulating spring, one end of which is connected with the cover and the other end is connected with the spool body.

2 - The right end of the cage is provided with a first oil port, and the circumference of the cage is provided with 2 rows of second oil ports.
