Air pockets in pipelines reduce flow efficiency, cause pressure fluctuations, and can lead to water hammer — this valve eliminates all of that automatically, without any manual intervention. Made from high-grade corrosion-resistant plastic (PVC\/polypropylene), it’s lightweight, chemical-resistant, and built for long-term outdoor and indoor use.\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1 inch (DN25) — BSP threaded connection for easy inline installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-grade PVC\/polypropylene — corrosion-resistant, UV-stable, and chemical-resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e Automatic — continuously vents trapped air without manual intervention\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e BSP male or female threaded — installs at high points in the pipeline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating:\u003c\/strong\u003e Suitable for low to medium pressure water supply and irrigation systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black or grey — standard plastic valve colour\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow It Works\u003c\/h3\u003e\u003cp\u003eThe air release valve is installed at the highest point of a pipeline where air naturally accumulates. When air enters the valve body, a float drops and opens a small orifice, allowing the air to escape. Once the air is released and water fills the valve body, the float rises and seals the orifice — preventing water from escaping. This cycle repeats automatically whenever air accumulates.\u003c\/p\u003e\u003ch3\u003eCommon Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAgricultural and garden irrigation systems\u003c\/li\u003e\n\u003cli\u003eWater supply and distribution pipelines\u003c\/li\u003e\n\u003cli\u003eBorehole and pump discharge lines\u003c\/li\u003e\n\u003cli\u003eWater storage tank inlet and outlet lines\u003c\/li\u003e\n\u003cli\u003eIndustrial fluid handling systems\u003c\/li\u003e\n\u003cli\u003eSwimming pool and water feature pipework\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Use an Air Release Valve?\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e✅ Prevents air locks — maintains full flow efficiency in pipelines\u003c\/li\u003e\n\u003cli\u003e✅ Reduces water hammer — protects pipes, fittings, and pumps from pressure surges\u003c\/li\u003e\n\u003cli\u003e✅ Automatic operation — no manual venting or maintenance required\u003c\/li\u003e\n\u003cli\u003e✅ Lightweight plastic body — corrosion-proof and easy to install\u003c\/li\u003e\n\u003cli\u003e✅ Standard BSP thread — fits most pipeline systems and fittings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Judema F-KD Enterprise","offers":[{"title":"Default Title","offer_id":48404417577210,"sku":null,"price":30.0,"currency_code":"GHS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0818\/2890\/5210\/files\/pvc-ball-valve-side-view.png?v=1775404386","url":"https:\/\/judemafkdshops.com\/products\/1-air-valve-plastic","provider":"Judema F-KD Enterprise","version":"1.0","type":"link"}
