Hydraulic Pressure Control Cartridge Valve 3 Innovations - China

price: 60.00 Dollar US$

AAK Hydraulic Pressure Control Cartridge Valve has 3 innovations, helped Joao solve the equipment vibration Pedro, one of our old Brazilian customers, introduced AAK to Joao in August last year.

I thanked Pedro for his trust, but also requested myself to thoroughly solve the problem of hydraulic pilot operated pressure control cartridge valve encountered by Joao for the trust of Pedro.

Trust is the lifeline of AAK cartridge valve, whether it is the production, promotion or marketing of cartridge valves.

Joao's customer tried to order 5 sets of hydraulic power units, but the commissioning was not smooth and the equipment vibrated too much.

Their engineer believed that the hydraulic pilot operated pressure control cartridge valve purchased by Joao was not up to the standard, and the change of the pilot pressure was delayed, resulting in the actuator action delay and vibration.

The original manufacturer of the hydraulic pressure control cartridge valve said that it was manufactured according to the customer's drawings and the accuracy was up to standard.

Joao was caught between supplier and engineer, which was very embarrassing.

Joao contacted his friend Pedro, which gave the opportunity for AAK cartridge valve to perform.

Joao's first email to us is as follows: Pedro told me that if there is any difficulty in cartridge valve, just contact AAK.

I stayed at AAK cartridge valve website for more than 7 minutes.

The fact that AAK solved difficult problems for customers showed me hope.

I told him that to avoid equipment vibration, the response speed of the hydraulic pilot operated pressure control cartridge valve should be increased first, and the pilot pressure should not lag, so as to avoid the opening lag of the counterbalance valve in the system.

After 45 days, AAK sent the samples of hydraulic pressure control cartridge valves.

Last week, Joao sent an email to inform us that with AAK hydraulic pilot operated pressure control cartridge valve installed, the commissioning of the hydraulic power unit was smooth and there was no vibration.

The customer was also satisfied.

AAK hydraulic pilot operated pressure control cartridge valve can improve the opening lag of the counterbalance valve in the system, because we have made innovations in 3 aspects, which most cartridge valve manufacturers have not expected.

1 - The vent cavity, ejector hole and control cavity of the hydraulic pressure control cartridge valve body are on the same axis.

The side wall of the valve body is provided with an oil outlet connecting the control chamber and the inclined hole.

The two oil ports of the valve body are respectively connected with the main oil circuit and the control chamber of the hydraulic system, forming two parallel connection channels.

2 - The spring seat of the hydraulic pressure control cartridge valve is located at the bottom of the ventilation chamber, the adjusting sleeve is threaded in the ventilation chamber, the adjusting bolt is connected in the threaded hole on the adjusting sleeve, and the first connecting channel has fixed hydraulic resistance parts connected in series with small holes.

3 - The side wall of the valve seat of the hydraulic pressure control cartridge valve is provided with a small hole to connect the inner hole of the valve seat with the annular cavity.

There is a steel ball in the lower cavity of the valve seat.

A return spring is installed in the cavity at the upper part of the valve base.

The upper end of the ejector rod conflicts with the lower end of the spring seat, while the lower end of the ejector rod conflicts with the steel ball.

The outer circumference of the ejector rod and the inner hole of the valve seat form a circular gap.

AAK hydraulic pilot operated pressure control cartridge valve, fast response, no vibration, you can also try it! AAK HYDRAULIC CARTRIDGE VALVES (513) 2023-02-25
