This valve head mounts directly onto compatible zone valve bodies to control flow in individual heating or cooling zones. The normally closed design ensures the valve defaults to a closed position on power loss, a key safety and energy-conservation characteristic. The integrated end switch terminals allow the valve head to signal the system circulator or boiler when the valve reaches the fully open position, enabling proper sequencing of hydronic system components. Installation is typically performed by licensed plumbers or HVAC technicians working on residential or light commercial hydronic systems.\u003c\/p\u003e\n\u003cp\u003eThis zone valve head is used in forced hot water (hydronic) heating systems where multiple zones require independent temperature control. The 24-volt operating voltage makes it compatible with standard low-voltage zone control systems commonly found in residential and light commercial buildings. The pop-top manual override feature allows a technician to manually open the valve during troubleshooting or system commissioning without applying power. Typical installations include baseboard heating loops, radiant floor heating zones, and fan coil unit circuits controlled by individual zone thermostats.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-volt operating voltage compatible with standard low-voltage hydronic zone controls\u003c\/li\u003e\n  \u003cli\u003eNormally closed (N\/C) design defaults to closed position on power loss\u003c\/li\u003e\n  \u003cli\u003ePop-top manual override for hands-on troubleshooting and commissioning\u003c\/li\u003e\n  \u003cli\u003eEnd switch terminals signal circulator or boiler on full valve open\u003c\/li\u003e\n  \u003cli\u003eDesigned for use as a zone valve head replacement in hydronic zoning systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement zone valve head for 24-volt normally closed hydronic zone valve assemblies requiring end switch functionality.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician familiar with hydronic systems. Power down the zone control panel and thermostat circuits before removing or installing the valve head. Ensure the replacement head is fully seated and locked onto the valve body before restoring power. Wiring connections at the end switch terminals should comply with applicable NEC low-voltage wiring requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Action\u003c\/strong\u003e: Normally Closed (N\/C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverride Type\u003c\/strong\u003e: Pop-Top Manual Override\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Switch\u003c\/strong\u003e: Yes, terminals included\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: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ag13a01a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51233280426290,"sku":"AG13A01A","price":108.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307629009.jpg?v=1780096110","url":"https:\/\/voomisupply.com\/products\/honeywell-ag13a01a-24v-zone-valve-head-end-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
