Hydraulic Direct-acting relief valve Equivalent to SUN RDBA

China [CN]

For Hydraulic Direct-Acting Relief Valve equivalent to SUN RDBA, AAK received the re-peat order from Spanish client after 1 year

Last May, we launched a hydraulic direct-acting relief valve equivalent to SUN standard part RDBA.

Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak, dirt tolerant, immune to silting and are very fast.

2 months after it was posted, we received the trial order from a new client in Spain. Per client, they will test the samples first. After it passed the testing, they will place the re-peat order for 500 pcs.

Last week, it was 13 months after the trial order was delivered, we received the re-peat order for 650 pcs from this Spanish client.
