It is a proportional (modulating) valve rather than a pop-type safety valve — as system vacuum approaches the set point, the valve bleeds in atmospheric air to hold the system at a safe, repeatable level.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrass body construction\u003c\/li\u003e\n\u003cli\u003eMale NPT (MNPT) inlet — available in 1\/4\", 3\/8\", 1\/2\", 3\/4\", and 1\"\u003c\/li\u003e\n\u003cli\u003eField-adjustable vacuum set point across a 0–28\" Hg range\u003c\/li\u003e\n\u003cli\u003eProportional \/ modulating relief — not a code (ASME-stamped) pop safety valve\u003c\/li\u003e\n\u003cli\u003eOperating temperature range approximately -65°F to 250°F\u003c\/li\u003e\n\u003cli\u003eNon-code: intended for vacuum-level protection, not ASME pressure relief\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eVacuum pumps, vacuum tanks and reservoirs, vacuum packaging and material-handling systems, and any process where the vacuum level must be limited to protect downstream equipment.\u003c\/p\u003e\n\u003cp\u003eSelect the MNPT size that matches your port.
