It maintains the correct air-to-water ratio inside a galvanized steel pressure tank, preventing waterlogging and preserving tank performance over time. The AV-57 features a durable plastic body with a polypropylene float, a 1\/4 inch pressure gauge port, and a 1-1\/4 inch male pipe thread (MPT) connection. The built-in air release valve is non-adjustable, simplifying installation and reducing the risk of miscalibration. This control is not compatible with precharged or bladder-style tanks. A licensed plumber or pump service technician is the typical installer for this type of device.\u003c\/p\u003e\u003cp\u003eThe AV-57 is intended for residential and light commercial deep well applications where a conventional galvanized pressure tank is in service. It automatically manages air charge within the tank as the pump cycles, keeping the system operating within proper pressure ranges. This part is sold in packages of 3 units, making it practical for service contractors stocking multiple jobs or performing scheduled maintenance across several sites.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMaintains proper air-to-water relationship in galvanized pressure tanks\u003c\/li\u003e\n\u003cli\u003eCompatible with deep well submersible pump systems\u003c\/li\u003e\n\u003cli\u003eDurable plastic body with polypropylene float for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1\/4 inch pressure gauge port for monitoring\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch MPT connection for straightforward pipe integration\u003c\/li\u003e\n\u003cli\u003eNon-adjustable air release valve reduces setup variables\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with deep well submersible pump systems paired with conventional galvanized pressure tanks.

Shut off power to the pump and relieve system pressure before removing or installing any pressure tank fittings. Apply appropriate thread sealant to the MPT connection per standard plumbing practice. Verify the tank type before installation — this control is not suitable for precharged tanks and must not be used in those applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-1\/4 inches MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Gauge Port\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloat Material\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Release Valve\u003c\/strong\u003e: Non-adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 units per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHLAND WATER GROUP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AV-57\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHLAND","offers":[{"title":"Default Title","offer_id":51523398992178,"sku":"AV-57","price":146.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2901590bfabd3a23de98413946c2115.jpg?v=1785441824","url":"https:\/\/voomisupply.com\/products\/ashland-water-group-av-57-air-volume-control","provider":"Voomi Supply","version":"1.0","type":"link"}
