The fully bronze body houses a spring-loaded check valve, an air relief valve with opening port, and two resilient-seated shutoffs with tee handles and test cocks. It operates across a temperature range of 32 to 140 degrees F and holds a maximum working pressure of 150 psi. A lightweight poppet seals the air opening under minimum flow conditions to reduce head loss. All internal components are serviceable in-line from the top of the unit, minimizing downtime during maintenance.\u003c\/p\u003e\n\u003cp\u003eThis vacuum breaker is suited for installation in industrial plants, cooling towers, laboratories, laundries, swimming pools, and lawn sprinkler systems where backflow prevention is required by code. It can be used with the SentryPlus Alert freeze sensor accessory (sold separately) to provide warning when ambient temperatures approach the freezing point. Optional union end ball valves and a plastic bonnet are available for additional freeze protection in cold-climate installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFully bronze body construction for durability in potable and non-potable water service\u003c\/li\u003e\n  \u003cli\u003eSpring-loaded check valve with air relief valve and opening port\u003c\/li\u003e\n  \u003cli\u003eTwo resilient-seated shutoffs with tee handles and integral test cocks\u003c\/li\u003e\n  \u003cli\u003eLightweight poppet design provides minimum head loss under low-flow conditions\u003c\/li\u003e\n  \u003cli\u003eAll internal parts serviceable in-line from the top — no need to remove the unit\u003c\/li\u003e\n  \u003cli\u003eCompatible with SentryPlus Alert freeze sensor accessory for cold-weather protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in industrial plants, cooling towers, laboratories, laundries, swimming pools, and lawn sprinkler systems requiring backsiphonage protection.

Shut off the water supply and depressurize the line before installing or servicing the unit. The PVB must be installed a minimum height above all downstream outlets as required by code — consult local authority having jurisdiction for specific elevation requirements. Do not install in a location subject to continuous submersion or back-pressure conditions, as this device is rated for backsiphonage prevention only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet \/ Outlet Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 32 to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Bronze\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Pressure Vacuum Breaker\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: t765dbv\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51267850076466,"sku":"T765DBV","price":197.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308912906.jpg?v=1780692121","url":"https:\/\/voomisupply.com\/products\/watts-t765dbv-3-4-inch-pressure-vacuum-breaker-bronze-pvb","provider":"Voomi Supply","version":"1.0","type":"link"}
