This valve is crucial for maintaining\r\nsystem performance by automatically venting air that can cause issues such as\r\nnoise and reduced efficiency. The valve is highly versatile, with a high-\r\ntemperature rating making it suitable for glycol systems and as an anti-vacuum\r\ndevice. It is engineered to handle the separation and dispersal of air while\r\nfluid circulates through the system, which helps to maintain smooth and\r\neffective operation. Key features include a 1\/8\" bottom tap and a 1\/8\" NPT\r\nmale threaded inlet, allowing for easy installation and integration into\r\nexisting systems. The valve is pressure rated up to 150 PSI (10 bar) and can\r\nhandle temperatures up to 240°F (116°C). For ease of maintenance, the valve\r\ncan be disassembled for inspection and cleaning, ensuring longevity and\r\nconsistent performance. Constructed from durable brass, the Watts FV-4 Series\r\nvalve is built to withstand the demands of light commercial and residential\r\nhydronic heating applications. The float mechanism is made from high-\r\ntemperature resistant polyethylene, enhancing reliability and extending the\r\nvalve's service life. At Watts, our family of brands offers one of the most\r\nvaried product lines in the world. Simply put, if you're moving, removing,\r\nheating, treating, or reusing water, we have everything you need to get the\r\njob done. Everything we design is made to keep the Earth's most precious\r\nresource safer, cleaner, and more useful for our customers. From melting ice\r\non entire city blocks from the ground up, to filtering safe drinking water in\r\nisolated, weather disaster zones, you need water and water needs Watts.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n \u003cul class=\"a\"\u003e\r\n \u003cli\u003eMaximum Pressure: 150 psi (10 bar)\u003c\/li\u003e\r\n \u003cli\u003eTemperature Range: 33F - 240F (5C - 116C)\u003c\/li\u003e\r\n \u003cli\u003eFloat is high temperature resistant polyethylene\u003c\/li\u003e\r\n \u003cli\u003eSuitable for use with glycol systems\u003c\/li\u003e\r\n \u003cli\u003eImpurities do not usually affect function as maximum float line of water is always lower than the valve seal\u003c\/li\u003e\r\n \u003c\/ul\u003e","published_at":"2026-05-04T17:58:34+10:00","created_at":"2026-05-04T17:58:31+10:00","vendor":"Watts Water Technologies","type":"Float Valves","tags":["industrial_April2026"],"price":12700,"price_min":12700,"price_max":12700,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":44214953246900,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B000MINF34","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Watts 0590715 1\/8\" FV-4M1 Automatic Float Vent","public_title":null,"options":["Default Title"],"price":12700,"weight":141,"compare_at_price":null,"inventory_management":"shopify","barcode":"783961246471","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/auspowers.com\/cdn\/shop\/files\/B000MINF34.jpg?v=1777993526"],"featured_image":"\/\/auspowers.com\/cdn\/shop\/files\/B000MINF34.jpg?v=1777993526","options":["Title"],"media":[{"alt":null,"id":32911566962868,"position":1,"preview_image":{"aspect_ratio":1.0,"height":1500,"width":1500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/B000MINF34.jpg?v=1777993526"},"aspect_ratio":1.0,"height":1500,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/B000MINF34.jpg?v=1777993526","width":1500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eWatts 0590715 1\/8\" FV-4M1 Automatic Float Vent\u003c\/h3\u003e\r\n\u003cp id=\"b\"\u003eThe Watts FV-4 Series automatic air vent valve is designed for both commercial\r\nand residential hydronic heating systems, ensuring efficient air removal in\r\nhot or cold water distribution systems.
