{"product_id":"conrader-blg-piloted-unloader-valve","title":"Conrader BLG Piloted Unloader Valve — 60 SCFM, 1\/2\" FNPT, 1\/4\" Pilot Inlet","description":"\u003cp\u003eThe Conrader BLG-Series piloted unloader valve controls a compressor by venting excess air to atmosphere once system pressure reaches the unload (cut-out) setting. The integral pilot stays closed until pressure builds to the set point, then opens and pressurizes the unloader, which vents the line; as pressure falls to the load (cut-in) setting the pilot closes and the system repressurizes. Rated to 60 SCFM with a 1\/2\" FNPT unloader and a factory-adjustable 20–250 psi range, the BLG is built for gas-engine-driven air compressors and other compressed-air systems.\u003c\/p\u003e\n\u003cp\u003eThis listing offers the BLG in two control configurations.
