Hydraulic Cartridge Proportional Relief Valve 3 Advantages - China
price: 60.00 Dollar US$
3 advantages of AAK Hydraulic Cartridge Proportional Relief Valve helped Francis win a big deal Francis is from a hydraulic equipment company in Spain, and has been purchasing smoothly for 5 years.
Some time ago, he was stumped by a hydraulic cartridge proportional relief valve.
The hydraulic proportional cartridge used in their customized hydraulic power unit was made by a local manufacturer.
The equipment commissioning was not smooth, and the hydraulic proportional relief cartridge responded slowly and leaked when the system was in a large flow state.
The original manufacturer tested the accuracy, and all of them reached the standard.
The engineer asked the original manufacturer to optimize the structure, but no result after 1 week.
Francis contacted several other manufacturers, but there was still no solution.
Francis was worried.
Francis noticed AAK in B2B and left us a message:
1 - The hydraulic cartridge proportional relief valve responds slowly, and there is a source of leakage?
2 - Can AAK optimize the structure of the hydraulic proportional relief cartridge?
3 - What is the cost and lead time? After communication, we learned the situation that Francis purchased the hydraulic cartridge proportional relief valves.
According to the drawings, the samples of the original manufacturer, and the requirements of equipment working conditions, AAK engineers judged that the problem was probably caused by structural hazards, and AAK was 90% sure to optimize the original structure.
Francis asked for AAK samples.
After 45 days, AAK sent 12 samples of hydraulic cartridge proportional relief valves.
1 month later, Francis informed us by email that with AAK samples, the trial run of the equipment was smooth, and the customer was satisfied and planned to place a large order.
Francis asked us to wait for the good news.
AAK hydraulic cartridge proportional relief valve can realize large flow rate, fast response speed and no leakage.
For these 3 advantages, we have made 3 optimizations on the structure: 1 - The valve body of the hydraulic cartridge proportional relief cartridge is provided with a stepped inner hole.
The side wall is provided with a stepped port.
The valve cage is connected to the lower part of the valve body.
On the side wall of the lower part of the valve cage, there is a flow passage cavity between the valve body and the valve body.
The upper part and the inner hole of the body form an oil return cavity and a flow passage hole.
2 - One end of the valve spool is slidably arranged in the inner hole of the valve cage, which can control the on-off of the through flow hole.
In the oil return chamber, the lower part of the spring is against the upper part of the spool, and the upper part forms a control chamber with the body.
The force on the spool can be changed according to the pressure of the control chamber.
3 - The body of the hydraulic cartridge proportional relief valve is also equipped with an electric proportional control system.
Its oil inlet is connected to the flow passage chamber, and its oil outlet is connected to the oil return chamber.
The pressure of the control chamber is changed by changing the voltage control signal of the electric proportional control system.
The optimized hydraulic cartridge proportional relief valve uses a small flow electric proportional control system to change the pressure of the control chamber,
