AAK Hydraulic Pilot-to-close Check Valve Equivalent to SUN COFA

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.

Last month, we received the good news from the customer that AAK samples
passed the durability testing for 2 million times, and the price is in the
middle among 3 manufacturers. But the manufacturer who has the lowest price
did not pass the durability testing for 2 million times. They will choose
AAK their preferred supplier for hydraulic screw-in cartridge valves.
 
AAK hydraulic pilot-to-close check valve E-COFA two advantages:
1. The function and performance is equivalent to that of SUN COFA
2. Its service life is longer than of its domestic peers

Technical parameters of AAK E-COFA hydraulic pilot-to-close check valve:
Max. Operating Pressure: 350 bar (5000 psi)
Flow: 40 gpm (160 L/min)

AAK E-COFA hydraulic pilot-to-close check valve, benchmarking SUN COFA, its
service life is 2 times that of its domestic peers. You are welcome to give
it a try.
