Hydraulic Cartridge Relief Valve Adjustable For 3 Pressures - China

Hydraulic Direct Acting Cartridge Relief Valve with 3 functions, AAK 1 valve replaced 3 valves of HydraForce Galeno is from Spain and has cooperated with AAK hydraulic valves for 5 years.

Some time ago, he sent me an email asking us to design a hydraulic direct acting cartridge relief valve to replace the 3 HydraForce standard hydraulic cartridge relief valves in his system.

After communication, we learned that their customer had customized a new equipment and was satisfied with their hydraulic power unit functions, but the customer found that the cost of the equipment had no advantage in the market.

Because the hydraulic components used are all standard parts, there is little possibility of price reduction.

Their engineers said that the only possibility is to use one hydraulic direct acting cartridge relief valve to realize the 3 functions of the 3 cartridge relief valves with different pressure controls in the system, and the system circuit is simplified.

Galeno contacted HydraForce for customization, but HydraForce was not willing to develop this non-standard part due to small quantity.

According to the schematic diagram of the hydraulic system provided by Galeno, and the drawings of 3 HydraForce standard parts, AAK engineers found the solution after discussion.

The hydraulic direct acting cartridge relief valve redesigned by AAK can replace the original 3 valves without affecting its function.

After 45 days, AAK sent 10 samples of hydraulic direct acting cartridge relief valves.

1 month after the samples of the hydraulic direct acting cartridge relief valve was sent, Galeno informed us by email that the equipment could work with AAK hydraulic direct acting cartridge relief valve, and its functions were not different from those original ones.

The prototype has been sent to the customer.

He said jokingly that everyone just needs to wait for a big order.

The hydraulic direct acting cartridge relief valve designed by AAK, is arranged with an oil return hole at the level of the front end of the poppet valve spool, a thrust belt is arranged around the front end, and an oil hole is arranged on the poppet valve spool.

There is a spring between the poppet valve spool and the pressure regulating screw plug in the valve body.

The vertical position at the front end of the poppet valve spool corresponds to a cylindrical oil chamber, which is connected with the oil inlet.

When the pressure oil enters from the oil inlet hole, if the thrust generated by the thrust ring is less than the set pressure of the spring, the poppet valve spool is closed.

When the thrust generated by the system is greater than the constant pressure of the spring, the pressure oil pushes the thrust ring to open the poppet valve spool, and the pressure oil flows back to the oil tank through the oil return hole.

No matter which pressure state is high, medium or low, the functions can be satisfied, and the hydraulic system is simplified.

AAK hydraulic direct acting cartridge relief valve is adjustable for 3 pressures.
