AAK Hydraulic Cartridge Relief Valve Equivalent to SUN RDDA

This week, we’d like to introduce a hydraulic cartridge relief valve equivalent to SUN RDDA. This Direct-acting relief cartridge is normally closed, pressure-limiting valve used to protect hydraulic components from pressure transients. 

In October, a customer in Russia found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. He sent us an inquiry with a list of over 40 model codes equivalent to SUN standard cartridge valves, the qty is 10 pcs each as the trial order. If testing is OK, the annual order will be 500 pcs – 1,000 pcs. 1 week after we sent the quotes, the customer advised that they feel AAK will be a very good fit for them, and they would like to visit AAK factory in November.

Last week, customer came to AAK factory and visited the entire production process, from raw material cutting, rough machining, fine machining, accuracy measuring, cleaning, assembling, etc.
