AAK Hydraulic Direct-Acting Relief Valve Equivalent to SUN RDFA

This week, we’d like to introduce a Hydraulic Cartridge Direct-Acting Relief Valve equivalent to SUN standard part RDFA.

The 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.

Last year, one of our Russian customers sent inquiry for model RDFA Direct-Acting Relief Valve, 10 pcs for trial order and 500 pcs for annual order. At that time, AAK did not have existing procedure for this model yet, and it takes at least 30 days for us to develop it.
