It combines three functions in a single brass body — a \u003cstrong\u003epilot valve\u003c\/strong\u003e, a \u003cstrong\u003edischarge unloader valve\u003c\/strong\u003e, and a \u003cstrong\u003echeck valve\u003c\/strong\u003e — eliminating separate components and the plumbing between them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow it works:\u003c\/strong\u003e The check valve prevents backflow as the compressor builds pressure. When downstream pressure reaches the unload setting, the pilot opens and pressurizes the unloader, venting excess air to the atmosphere so the engine runs unloaded. As air is used and pressure drops to the load setting, the pilot closes, the unloader reseats, and the cycle repeats.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax flow capacity:\u003c\/strong\u003e 30 SCFM @ 100 psig\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnload set pressure range:\u003c\/strong\u003e 40–250 psig\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet pressure differential:\u003c\/strong\u003e 10–50 psid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating temperature:\u003c\/strong\u003e −65°F to 400°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection sizes:\u003c\/strong\u003e 1\/8\" to 3\/4\" (−2 to −12)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection types:\u003c\/strong\u003e NPT, BSPT, compression, SAE 45° flare, JIC 37° flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody \u0026amp; fittings:\u003c\/strong\u003e brass  |  \u003cstrong\u003epoppets:\u003c\/strong\u003e reinforced PTFE  |  \u003cstrong\u003esprings:\u003c\/strong\u003e stainless steel  |  \u003cstrong\u003eO-rings:\u003c\/strong\u003e silicone\/Viton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnloader outlet:\u003c\/strong\u003e muffler (standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e gas-engine driven air compressors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBuilt to order\u003c\/h3\u003e\n\u003cp\u003eThe NG-Series is available in dozens of inlet and outlet configurations and any pilot load\/unload pressure setting within range.
