AAK Hydraulic Cartridge Counterbalance Valve Equivalent to SUN CBBA

This week, we’d like to introduce a Hydraulic Cartridge Counterbalance
Valve equivalent to SUN standard part CBBA.

Counterbalance valves with pilot assist are meant to control an overrunning
load. The check valve allows free flow from the directional valve (port 2)
to the load (port 1) while a direct-acting, pilot-assisted relief valve
controls flow from port 1 to port 2. Pilot assist at port 3 lowers the
effective setting of the relief valve at a rate determined by the pilot
ratio.

In the year of 2022, a new customer from Turkey sent us inquiry for SUN
model CBBA cartridge counterbalance Valve, 10 pcs for trial order and 100
pcs for annual order. After we quoted the price, we were advised that the
competition in Turkey market is very fierce, AAK price is too high. That was
not the first time that we received this type of feedback from Turkey
customers, so we did not expect to receive any order from this customer.
However, in September of 2022, the customer sent us inquiry for CBBA
cartridge counterbalance Valve again. Feeling the real needs of this
customer, AAK gave a 8% discount and the customer placed the trial order for
10 pcs of samples for testing. After that, we did not receive any further
news from this customer. We thought that the customer may not approve the
quality of AAK samples.

Unexpectedly, 1 year later, in December, the last month of 2023, we received
the regular order for 100 pcs of CBBA hydraulic cartridge counterbalance
valve. Then we know that actually, AAK samples passed the testing, due to
the earthquake in Turkey and some internal changes in the company, the
customer’s buying plan was affected, so they held the order.
