The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat and protecting the compressor from liquid slugging. This valve is identified by its AJB-0\/55 designation and features a 2 x 3 ODF connection configuration, making it a direct-fit component for the refrigeration circuits it was engineered to serve. Installation is performed by licensed refrigeration or HVAC-R technicians as part of a system service or retrofit procedure.\u003c\/p\u003e\n\u003cp\u003eThis expansion valve is intended for commercial refrigeration applications, including walk-in coolers, reach-in cases, and similar low- or medium-temperature commercial appliance systems where precise refrigerant metering is required. The AJB-0\/55 model designation and ODF connection sizing are key identifiers when sourcing a replacement during a service call or planned maintenance. Technicians should verify the valve's superheat setting and refrigerant compatibility match the existing system before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThermostatic expansion valve (TXV) design for precise refrigerant metering and superheat control\u003c\/li\u003e\n  \u003cli\u003eAJB-0\/55 model designation for direct OEM-style replacement in compatible MASTER-BILT systems\u003c\/li\u003e\n  \u003cli\u003e2 x 3 ODF connection configuration for standard brazed-joint installation\u003c\/li\u003e\n  \u003cli\u003eEngineered for commercial refrigeration duty cycles and operating conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement TXV for MASTER-BILT commercial refrigeration equipment requiring the AJB-0\/55 valve with a 2 x 3 ODF connection.

Recover all refrigerant from the system before removing the existing valve, in accordance with EPA Section 608 regulations. ODF connections require brazing with appropriate silver-alloy filler material; use nitrogen purge during the brazing process to prevent internal oxidation. After installation, leak-check the system and verify superheat readings before returning the equipment to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Thermostatic Expansion Valve (TXV)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel Designation\u003c\/strong\u003e: AJB-0\/55\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: 2 x 3 ODF\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: MASTER-BILT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 09-09659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MASTER-BILT","offers":[{"title":"Default Title","offer_id":51207330627890,"sku":"09-09659","price":160.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307146693.jpg?v=1779727118","url":"https:\/\/voomisupply.com\/products\/master-bilt-09-09659-expansion-valve-txv-ajb-0-55","provider":"Voomi Supply","version":"1.0","type":"link"}
