AAK optimized Hydraulic Pilot-Operated Cartridge Relief Valve with 3 Skills, and Chandle placed a large order during CNY

China [CN]

Today is the first day of CNY's return to work. I opened mailbox and was full of surprises, especially the Mexican customer Chandler that we followed up for more than 1 year, placed an order, a large order of 1,200 hydraulic pilot operated cartridge relief valves. This is the happiest thing today. Chinese people pay attention to a good start, which represents hope, and also luck. 2023, I'm coming.

A year ago, Chandler left a message on AAK Hydraulic Valve website: Can AAK ensure that the hydraulic pilot operated cartridge relief valve is stable and fault-free within 1 year? As soon as I saw this message, I guessed that he was troubled by the quality of the hydraulic pilot operated cartridge relief valve. After communication, it was learned that the cartridge relief valve produced by the original manufacturer was unstable and had a service life of less than 6 months, which caused their hydraulic winch to be complained because of its unstable operation and inability to rise. According to the drawing provided by him, AAK engineers found that the hydraulic system had a great impact on the valve spool and was greatly worn, so it was necessary to optimize the original structure of the hydraulic pilot operated cartridge relief valve. Chandler was a little dubious. After he learned that the shape and size of the hydraulic pilot operated cartridge relief valve would not need to be changed, he asked for AAK samples. After 35 days, AAK sent 20 hydraulic pilot operated cartridge relief valves.

3 weeks later, Chandler just told us that AAK hydraulic pilot operated cartridge relief valve could be installed in their system and the equipment operated normally, then there was no further information. 1 month later, I wrote an email to follow up, but there was no reply. Some time ago, we recommended a new model of hydraulic pilot operated cartridge relief valve equivalent to SUN hydraulics, and there was still no reply. Until CNY, he took the initiative to email us and placed a large order. 

Chandler said that after nearly 1 year of comparison and test, AAK hydraulic pilot operated cartridge relief valve has no problems in function, is stable, and its performance is satisfactory, and it is durable for 1 year without worry. AAK hydraulic pilot operated cartridge relief valve can quickly and stably overflow, can be adjusted remotely, and is durable, due to 3 special structures:

1. Inside the main valve spool of the cartridge relief valve, there is a spring connected with the inner wall of the valve body. In the upper space of the valve body, there is a pilot valve spool. The outer circle of the pilot valve spool is covered with a spring connected with the inner wall of the valve body. The two springs are inconspicuous, but effectively reduce the impact on the valve spool and improve the service life of the valve spool.

2. One side of the main valve spool is provided with a damping hole that can be connected with the inlet. The damping hole is connected with the position of the pilot valve spool, which can quickly and stably overflow.

3. A remote control port is set on the valve body, and the remote pressure regulation can be implemented by adjusting the hydraulic pressure at the upper end of the main valve spool.

AAK hydraulic pilot operated cartridge relief valve, has stable function, satisfactory performance, and is durable for more than 1 year without worry. Welcome to try it!
