The valve adapts to changing line pressure to maintain a steady flow rate in the downstream piping (see \"Principles of Operation\") without automation (neither electricity nor an air supply is required). These are not recommended for use with viscous fluids, fluids with high specific gravities, or fluids that contain debris or suspended solids. Accurate to +\/- 6 percent of desired flow rate, and can be adjusted without removing the valve from a line.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal Applications Include:\u003c\/strong\u003e\u003cbr\u003eChemical processing, aquariums, mining, water treatment, swimming pools, salt water, semiconductor\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBody and bonnet are of solid PVC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAll wetted parts are of thermoplastic and elastomeric materials for superior corrosion resistance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eA preset constant flow rate is maintained by automatically regulating orifice opening area, responding to changes of pressure differentials across the valve\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eVertical or horizontal installations\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFlow rate accuracy: +\/- 6 percent of full scale flow rate (water at ambient temperature)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFlow rate range ability: 20:1 maximum\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHandwheel permits on\/off opening and closing\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHandwheel serves as a mechanism by which the flow rate setting may be adjusted without shutting down the pipeline\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSprings of stainless steel 304 with PCTFE coating tested for long cycle life\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrescribed flow setting is clearly visible on the indicator at the top\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eAsahi Part Numbers:\u003c\/strong\u003e 1307005B, 1307005C, 1307007B, 1307007C, 1307010A, 1307010B, 1307010C, 1307020A, 1307020B, 1307020C, 1307030A, 1307030B, 1307030C, 1307030D, 1307040C, 1307040D\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Asahi","offers":[{"title":"1\/2 in. \/ 0.176 - 3.5","offer_id":47325218701524,"sku":"4320-B","price":1201.0,"currency_code":"USD","in_stock":true},{"title":"1\/2 in. \/ 0.35 - 3.52","offer_id":47325218734292,"sku":"4320-C","price":1223.0,"currency_code":"USD","in_stock":true},{"title":"3\/4 in. \/ 0.26 - 5.28","offer_id":47325218767060,"sku":"4321-B","price":1373.0,"currency_code":"USD","in_stock":true},{"title":"3\/4 in. \/ 0.53 - 5.28","offer_id":47325218799828,"sku":"4321-C","price":1373.0,"currency_code":"USD","in_stock":true},{"title":"1 in. \/ 2.20 - 8.81","offer_id":47325218832596,"sku":"4322-A","price":1619.0,"currency_code":"USD","in_stock":true},{"title":"1 in. \/ 0.441 - 8.81","offer_id":47325218865364,"sku":"4322-B","price":1619.0,"currency_code":"USD","in_stock":true},{"title":"1 in. \/ 0.881 - 8.81","offer_id":47325218898132,"sku":"4322-C","price":1619.0,"currency_code":"USD","in_stock":true},{"title":"2 in. \/ 8.81 - 35.22","offer_id":47325218930900,"sku":"4323-A","price":2934.0,"currency_code":"USD","in_stock":true},{"title":"2 in. \/ 1.76 - 35.22","offer_id":47325218963668,"sku":"4323-B","price":2934.0,"currency_code":"USD","in_stock":true},{"title":"2 in. \/ 3.52 - 35.22","offer_id":47325218996436,"sku":"4323-C","price":2934.0,"currency_code":"USD","in_stock":true},{"title":"3 in. \/ 22.02 - 88.07","offer_id":47325219029204,"sku":"4324-A","price":4902.0,"currency_code":"USD","in_stock":true},{"title":"3 in. \/ 44.03 - 88.07","offer_id":47325219061972,"sku":"4324-B","price":4902.0,"currency_code":"USD","in_stock":true},{"title":"3 in. \/ 8.81 - 88.07","offer_id":47325219094740,"sku":"4324-C","price":4902.0,"currency_code":"USD","in_stock":true},{"title":"3 in. \/ 66.04 - 132.1","offer_id":47325219127508,"sku":"4324-D","price":4902.0,"currency_code":"USD","in_stock":true},{"title":"4 in. \/ 44.03 - 264.2","offer_id":47325219160276,"sku":"4325-C","price":7507.0,"currency_code":"USD","in_stock":true},{"title":"4 in. \/ 132.10 - 264.2","offer_id":47325219193044,"sku":"4325-D","price":7507.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/2424\/0340\/files\/products_Asahi_Constant_Flow_Valve.jpg?v=1765199224","url":"https:\/\/alscoind.com\/products\/constant-flow-valves","provider":"Alsco Industrial","version":"1.0","type":"link"}
