This positive action avoids dribble, reduces noise and allows full flow until the selected closed level is reached. Inherent in the design is a non-adjustable operating differential in water level between opening and closing of approximately 75mm. Also available in stainless steel for use in demanding environments such as desalination plants and sea water.\u003c\/p\u003e","brand":"Purewater","offers":[{"title":"Default Title","offer_id":56703724912965,"sku":"A\/K20","price":340.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/4595\/6165\/files\/1828_2005.jpg?v=1767798842","url":"https:\/\/tanks-direct.co.uk\/products\/3-4-aylesbury-keraflo-k-type-sf-delayed-action-float-valve-20mm","provider":"Tanks Direct","version":"1.0","type":"link"}
