The ball valve name derived from the flow-controlling ball valve located within the body of the valve. A hole through the center of the ball along one axis connects the inlet and outlet ports of the body. The ball itself is held in place by PTFE seats and rotates 90 degrees within. These provide permanent lubrication and keep the valve \"bubble-tight.\" They are backed by elastomeric cushions, which provide pressure against the ball and, at the same time, compensate for wear. Elastomer O-rings are used for stem and carrier seals to prevent leakage to the atmosphere. In the open position, the flow is straight-through, and there is minimal pressure drop when the porting through the ball is the same size as the inside diameter of the pipe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal Applications Include:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eI\u003cspan\u003esolation valves, water treatment, water features, fountains, aquariums, landfills, swimming pools, power plants, mining, transportation, chemical processin\u003c\/span\u003eg\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePVC body\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEPDM or FKM seals\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTrue union design\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEqual percentage flow characteristics\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePrecision machined flow control ball and seat design\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSST - Seat Support Technology\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDegreed indicator plate (manual type)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIndicator line on handle (manual type)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFlow direction arrow label\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHandle doubles as carrier adjustment tool\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eISO 5211 top flange bolt pattern\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIntegrally molded base pad for panel mounting\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDual stem O-rings\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eOptions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eElectric actuation with 4-20 mA control\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003ePneumatic actuation with 4-20mA control\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eStem extension\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e2î square operating nut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!----\u003e","brand":"Alsco","offers":[{"title":"1\" FKM Soc\/Thr","offer_id":48946337087701,"sku":"","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/1881\/6981\/files\/pvc-type-21-sst-flow-control-ball-valve-449848.webp?v=1756182744","url":"https:\/\/expertpowerwash.com\/products\/pvc-type-21-sst-flow-control-ball-valve","provider":"Expert Power Wash","version":"1.0","type":"link"}
