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.
