AAK Hydraulic Pressure Control Cartridge Valve, 3 selling points, helped Evander

Evander is from a hydraulic equipment manufacturing company in Greece. He has been in purchasing for 3 years smoothly. Last March, they tested a hydraulic power unit. The hydraulic pressure control cartridge valve used was from a local manufacturer. During equipment commissioning, the operation was unstable. The sensitivity of the hydraulic pressure control cartridge valve port became dull under the influence of oil pressure in the oil circuit when it is open or closed. The original manufacturer had no solution. Evander contacted several other hydraulic cartridge valve manufacturers for inquiry, but no result. He was very worried.

Evander searched AAK website on Google and noticed that AAK has solved the problem of hydraulic cartridge valves for customers many times. He left a message: Can AAK make the hydraulic pressure control cartridge valve stable, and open and close sensitively? After communication, we learned that he was facing difficulties in the test run. According to his hydraulic pressure control cartridge valve drawing and system schematic diagram, AAK engineers analyzed that as long as the original structure of the hydraulic pressure control cartridge valve was optimized, the problem could be solved. Evander saw the hope and requested AAK to make 20 samples. After 45 days, AAK delivered the samples of 20 hydraulic pressure control cartridge valves.

8 months later, Evander sent the first order of 500 hydraulic pressure control cartridge valves. Their customer was satisfied with their hydraulic power unit prototype, which operated stably and opened and closed sensitively, so the first order quantity was also surprising. AAK can replace the local cartridge valve manufacturer in Greece, the key point is that AAK hydraulic cartridge pressure control valve has two-way control oil circuit for opening and closing valves, which has high sensitivity, stable operation, and good reliability. We optimized it from 3 points:

1. The hydraulic cartridge pressure control valve spool has the conduction characteristic, and the valve spool structure is composed of the upper closed valve oil cavity cylindrical surface, the lower open valve oil cavity cylindrical surface, and the middle seal isolation boss cylindrical surface. The through cavity in the valve spool is composed of cylindrical through holes and boss holes at the upper and lower ends.

2. The valve spool mounting hole on the valve body is composed of 4 cylindrical stepped holes from top to bottom, and the diameter decreases from top to bottom. The upper end of the fourth step hole has a sealing cone, the lower end of the third step hole has a side wall of the valve body, and there is an oil inlet of the main oil circuit, and the fourth step hole is an oil outlet of the main oil circuit.
