Dramm recommends using its overhead nozzles together with Run-Out Valves and No-Drip Risers to control that drip. They solve the same problem from opposite ends: one drains the pipe, the other lifts the nozzle above it.\u003c\/p\u003e\u003cp\u003eThese are complements rather than alternatives, and they are bought on completely different quantity bases. The Run-Out Valve is a line-end part - one per pipeline run. Dramm designs it to be installed at the end of a 1 in or 3\/4 in PVC pipeline, where it opens when the water is turned off and lets the line run out, eliminating drip. The No-Drip Riser is a per-nozzle part, so it is ordered in the same quantity as the nozzles: it elevates a Dramm irrigation nozzle 2 1\/4 in above the pipeline so that when flow stops, the water left in the riser falls back into the pipe rather than out of the nozzle. A well set-up overhead line usually uses both.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRun-Out Valve\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 in, installs at the end of a 1 in or 3\/4 in PVC pipeline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRun-Out Valve action\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOpens when the water is turned off so the line drains\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNo-Drip Riser\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eElevates a Dramm irrigation nozzle 2 1\/4 in above the pipeline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNo-Drip Riser action\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eResidual water falls back into the pipeline instead of out of the nozzle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eQuantity basis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOne run-out valve per pipeline run; one riser per nozzle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eConfigurations\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eNo-Drip Riser\u003c\/td\u003e\n\u003ctd\u003eNDR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRun-Out Valve - 1 in PVC\u003c\/td\u003e\n\u003ctd\u003eROV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRemoves the post-shutoff drip that causes wet spots under an overhead line\u003c\/li\u003e\n\u003cli\u003eRun-Out Valve drains the pipeline automatically every time the zone closes\u003c\/li\u003e\n\u003cli\u003eNo-Drip Riser needs no moving parts - it works on height alone\u003c\/li\u003e\n\u003cli\u003eRiser suits Dramm overhead irrigation nozzles\u003c\/li\u003e\n\u003cli\u003eBoth parts are inexpensive relative to the crop damage a dripping line causes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOutdoor and greenhouse overhead irrigation over container stock\u003c\/li\u003e\n\u003cli\u003eNursery beds where post-shutoff drip causes wet spots and disease\u003c\/li\u003e\n\u003cli\u003eAny 3\/4 or 1 in PVC overhead line that holds water after the valve closes\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eUse with Dramm overhead nozzles such as Pin-Perfect, Nifty and Misty Mist, mounted on the PN-2010 threaded or PN-2020 slip fit pipe nipples.\u003c\/em\u003e\u003c\/p\u003e","brand":"Dramm","offers":[{"title":"Run-Out Valve - 1 in PVC","offer_id":52800280854839,"sku":"ROV","price":18.34,"currency_code":"USD","in_stock":true},{"title":"No-Drip Riser","offer_id":52800280887607,"sku":"NDR","price":2.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/ROV.jpg?v=1786404457","url":"https:\/\/www.blacklabelsupply.io\/products\/dramm-overhead-line-drip-control-run-out-valve-and-no-drip-riser","provider":"BLACK LABEL","version":"1.0","type":"link"}
