It accepts a maximum supply pressure of 400 psi and delivers a regulated output across a range of 10 to 400 psi, making it suitable for high-pressure pneumatic circuits where manual adjustment is impractical or unsafe. The regulator is equipped with a relief function, allowing downstream pressure bleed-off when pilot signal is reduced. Constructed from zinc and aluminum, the body balances durability with weight. It weighs 3.13 pounds and connects via 1\/2-inch NPTF end connections. Installation is performed by licensed pipefitters, pneumatic system technicians, or industrial maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThe NORGREN 11-042-003 is intended for compressed air service in industrial and commercial settings where pilot-operated pressure regulation is required. Typical applications include automated assembly lines, pneumatic control panels, and process equipment where a remote air signal governs downstream pressure rather than a manual handwheel. The regulator handles a maximum air flow of 300 CFM, making it appropriate for moderate- to high-flow pneumatic circuits. The 1\/2-inch NPTF port size is compatible with standard industrial compressed air piping. A 1\/2-inch gauge port thread is present for optional pressure gauge installation, though no gauge is included.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAir pilot operated design enables remote or automated pressure regulation without manual adjustment\u003c\/li\u003e\n\u003cli\u003eOperating range of 10 to 400 psi covers a broad spectrum of industrial pneumatic applications\u003c\/li\u003e\n\u003cli\u003eBuilt-in relief function vents downstream pressure when pilot signal drops\u003c\/li\u003e\n\u003cli\u003eMaximum air flow of 300 CFM supports high-demand pneumatic circuits\u003c\/li\u003e\n\u003cli\u003e1\/2-inch NPTF end connections for leak-resistant threaded pipe joints\u003c\/li\u003e\n\u003cli\u003eZinc and aluminum construction provides corrosion resistance at industrial operating temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 11-042-003 belongs to the NORGREN Series 11-042 and is designed for compressed air service in industrial pneumatic systems using 1\/2-inch NPTF piping with supply pressures up to 400 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and lock out the compressed air supply completely before connecting or disconnecting the regulator. Apply thread sealant rated for compressed air service to all NPTF connections and verify for leaks after pressurization. Confirm the pilot air signal source is properly sized and regulated before commissioning the unit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulator Type\u003c\/strong\u003e: Air Pilot Operated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Supply Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 10 to 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Air Flow\u003c\/strong\u003e: 300 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Port Thread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Gauge Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Function\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid Type\u003c\/strong\u003e: Compressed Air\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: 0 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc and Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 11-042\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORGREN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11-042-003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORGREN","offers":[{"title":"Default Title","offer_id":51701550612786,"sku":"11-042-003","price":1544.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b2e13eda2bece16aa80aa00e0157895.jpg?v=1788401255","url":"https:\/\/voomisupply.com\/products\/norgren-11-042-003-air-pilot-operated-regulator-400-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
