For Hydraulic Pilot-to-close check valve equivalent to SUN COJA, AAK received the trial order from a Customer in Germany

This week, we’d like to introduce a hydraulic Pilot-to-close check valve equivalent to SUN COJA. This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio.

Before CNY, we received an inquiry from a new customer in Germany for many cartridge valves, including SUN COJA Pilot-to-close check valve. This cartridge valve is not very commonly used, and there are only a few hydraulic cartridge valve manufacturers in Ningbo China that have this model in stock. Per customer, they have followed up hydraulic cartridge valve manufacturer AAK for a long time, and would like to place a trial order for 10 pcs for SUN COJA first. If the valves passed testing, they will place the annual order for 500 pcs.

We are confident to become the preferred hydraulic cartridge valve supplier for this customer in Germany, because AAK quality has been approved for many European customers.
