Rated at 100 PSI with 1\/2 inch ODF connections on the discharge, condenser, and receiver ports, this valve limits refrigerant flow from the condenser and bypasses hot gas around the condenser to the receiver when ambient temperatures drop. The valve body is brass with copper connections and features a knife edge metal-to-metal seat for reliable shutoff. This unit ships without a strainer and carries a maximum rated pressure of 500 PSIG. It is installed by licensed HVAC-R technicians as part of a head pressure control strategy in commercial and light commercial refrigeration or air conditioning systems.\u003c\/p\u003e\n\u003cp\u003eThe 903031 is suited for use in systems that operate year-round or in regions where outdoor ambient temperatures regularly fall below the design minimum for the condensing unit. Typical applications include rooftop air conditioners, remote condensing units, and refrigeration systems where maintaining adequate head pressure is required for proper metering device operation and system efficiency. The LAC valve body type is a standard configuration in Sporlan head pressure control assemblies. No specific compatible model numbers or system families were provided by the manufacturer for this listing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100 PSI pressure range for low ambient head pressure control\u003c\/li\u003e\n  \u003cli\u003eBrass valve body with copper ODF connections for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eKnife edge metal-to-metal seat provides positive, leak-resistant shutoff\u003c\/li\u003e\n  \u003cli\u003eDomed steel element for reliable pressure response\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch ODF discharge, condenser, and receiver connections for straightforward field piping\u003c\/li\u003e\n  \u003cli\u003eShips without strainer — allows use with externally installed filter-drier or strainer assemblies\u003c\/li\u003e\n  \u003cli\u003e500 PSIG maximum rated pressure supports a range of common refrigerants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation low ambient head pressure control valve for air-cooled condensing systems using 1\/2 inch ODF refrigerant piping connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a certified HVAC-R technician holding an EPA Section 608 certification. The system must be recovered, de-pressurized, and isolated before brazing or making any refrigerant circuit connections. Follow all applicable mechanical codes and the equipment manufacturer's piping diagrams when orienting and connecting discharge, condenser, and receiver ports. Do not apply torch heat directly to the valve body during brazing — use wet rags or a heat sink to protect internal components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 100 PSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Rated Pressure\u003c\/strong\u003e: 500 PSIG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDischarge Connection\u003c\/strong\u003e: 1\/2 inch ODF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondenser Connection\u003c\/strong\u003e: 1\/2 inch ODF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReceiver Connection\u003c\/strong\u003e: 1\/2 inch ODF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Body Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Connection Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eElement Type\u003c\/strong\u003e: Domed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeat Material\u003c\/strong\u003e: Metal to Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Joint Type\u003c\/strong\u003e: Knife Edge Metal to Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Body Type\u003c\/strong\u003e: LAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrainer Type\u003c\/strong\u003e: Less Strainer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Regulating Valve Type\u003c\/strong\u003e: Low Ambient Head Pressure Control\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Parker Hannifin Corporation\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: SPORLAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 903031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPORLAN","offers":[{"title":"Default Title","offer_id":51524956127538,"sku":"903031","price":373.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3146f8f62428083b1a9ccd202be1129a.jpg?v=1785462222","url":"https:\/\/voomisupply.com\/products\/sporlan-903031-low-ambient-head-pressure-control-valve-100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
