This valve features a 1\/2 inch BSP male thread inlet, facilitating easy installation into a 19mm x 1\/2\" BSP female iron tee. Its primary functions are to release air from the drip line when the system is activated and to permit air entry when the system is off, thus preventing a vacuum that could draw debris into the drip line, a condition known as \"suck back.\" Proper installation at the highest point in the system is crucial for optimal performance, and it is recommended to install one valve for every 40Lpm of water flow. This valve is not suitable for low-pressure applications, requiring a minimum operating pressure of 7 meters (70kPa).\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAllows clean air to enter the drip system.\u003c\/li\u003e\n\u003cli\u003eVents air out during system startup to eliminate air pockets.\u003c\/li\u003e\n\u003cli\u003e1\/2 inch BSP male thread for easy installation.\u003c\/li\u003e\n\u003cli\u003ePrevents \"suck back\" to avoid debris entry and potential blockages.\u003c\/li\u003e\n\u003cli\u003eRequires minimum operating pressure of 7 meters (70kPa).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n\u003ctd\u003e70mm x 65mm x 65mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.068kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eGrey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003e102646\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eThe Holman Poly Air Release Inline Valve 1\/2 Inch Plastic Prevents Suck Back is a reliable solution for drip irrigation systems.\u003c\/p\u003e","brand":"Holman","offers":[{"title":"Default Title","offer_id":47671401152729,"sku":"ING3120089","price":25.3,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/6599\/0873\/files\/692a5bfdf06f4ed3bad7ebcb65aa78ef.jpg?v=1767424297","url":"https:\/\/auzzistore.com.au\/products\/holman-poly-air-release-inline-valve-1-2-inch-plastic-prevents-suck-back","provider":"Auzzi Store","version":"1.0","type":"link"}
