Product Description
The Hydac 3022444 DR08-01-C-N-300V is a direct acting, spool type pressure reducing and relieving cartridge valve designed for hydraulic systems requiring constant secondary pressure regulation. This screw-in cartridge features an internal spring chamber drain and serves dual functions as both a pressure regulator and relief valve from the reduced pressure port to tank.
