AAK Hydraulic Counterbalance Valve Equivalent to SUN CBGG

This week, we’d like to introduce a Hydraulic Screw-in Counterbalance Valve
equivalent to SUN standard part CBGG.

The 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.

A customer in Spain sent us inquiry for this counterbalance valve last
September, with annual qty of 600 pcs. However, after we quoted the price,
there was no any feedback. The customer sent us inquires for other SUN
cartridge valves at later times. Every time, there was no any feedback.

Unexpectedly, this March, the customer got back to us and placed the trial
order of 10 pcs for CBGG. Until that time, we learned that AAK prices were
5% - 10% higher than other hydraulic cartridge valve manufacturers in China
every time, so he placed the orders with other manufacturers. However, the
quality of hydraulic cartridge valves he purchased from other hydraulic
cartridge valve manufacturers in Ningbo was not stable, he was very
frustrated, so he wanted to test AAK quality. We delivered the 10 pcs of
test samples.

Last week, we were very happy to learn that AAK samples passed the testing.
They are still performing very well after 9 months of use. The customer
placed their annual order with AAK finally. It has been 15 months since we
received the inquiry for this counterbalance valve CBGG.
