It features 1\/2 inch female pipe thread (FPT) inlet and outlet connections, plus a dedicated 1\/2 inch FPT bottom connection for expansion tank installation. A built-in stainless steel strainer protects the valve disc from fouling, and a tight-seating check feature prevents backflow. Licensed plumbers and HVAC technicians install this valve during new boiler commissioning or as a replacement in residential and light commercial hot water heating systems.\u003c\/p\u003e\n\u003cp\u003eThis regulator is suited for residential and light commercial hydronic heating systems. It fills the boiler and system piping with supply water and maintains set operating pressure during normal system operation. The fast-fill feature accelerates initial fill and purges air from the piping, reducing commissioning time. A manual purge lever is included for field use. In the event of minor system leaks, the valve provides automatic make-up water to keep the system pressurized and operating.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch FPT inlet and outlet connections for standard pipe installation\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch FPT bottom connection for direct expansion tank hookup\u003c\/li\u003e\n  \u003cli\u003eFast-fill feature speeds initial system fill and air purging\u003c\/li\u003e\n  \u003cli\u003eManual purge lever included for field servicing\u003c\/li\u003e\n  \u003cli\u003eStainless steel strainer protects valve disc from debris fouling\u003c\/li\u003e\n  \u003cli\u003eTight-seating check feature prevents backflow into supply line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation feed valve for residential and light commercial hydronic hot water boiler systems using 1\/2 inch female pipe thread connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the cold water supply and depressurize the boiler system before removing an existing regulator or installing this valve. Use thread sealant or PTFE tape on all pipe thread connections and verify there are no leaks before restoring system pressure. Do not exceed the valve rated pressure range during fast-fill or normal operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Female Pipe Thread (FPT) inlet, outlet, and bottom port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrainer Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 12 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 25 pounds\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 BRASS TUBULAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1156F  1\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51560556200242,"sku":"1156F  1\/2","price":1244.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6013be688ea8bbac7843657c5858effc.jpg?v=1786453768","url":"https:\/\/voomisupply.com\/products\/watts-brass-tubular-1156f-1-2-boiler-feed-regulator","provider":"Voomi Supply","version":"1.0","type":"link"}
