The unit handles a maximum flow of 7.8 GPM and is rated for temperatures up to 190°F, with 3/8" FNPT inlet, 3/8" FNPT outlet, and 3/8" FNPT bypass ports, and it weighs about 2.1 lb; the Mfg part number is AL607 and the BEP-AL607 designation identifies this model as part of the BE Pressure Supply lineup. This AL607 is commonly used as a replacement unloader for Arrowline/BE Pressure Supply-equipped machines operating under 4,200 psi.
