| Message: | This week, we’d like to introduce a hydraulic pilot-to-close check valve equivalent to SUN COFA, a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio.
Last October, we received an inquiry from a new customer in the United States for SUN COFA 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 placed the trial orders with 3 manufacturers, and will do durability testing at the same time. The one who has the best performance in the testing will be their preferred supplier.
