The valve features a brass body with an NBR elastomer seal, a 1\/2 inch NPT port, and a 5\/8 inch orifice. It accepts a wide range of input voltages including 12 volts DC, 24 volts DC, 24\/60 volts AC, 120 volts DC, 120\/60 to 110\/50 volts AC, and 240\/60 to 220\/50 volts AC, making it adaptable to many control circuit configurations. Maximum working pressure is 40 psi. A coil is included, though the valve requires an integrated coil for complete assembly. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis solenoid valve is suited for use in residential and commercial fluid control systems where a normally closed, de-energized shutoff position is required. Typical applications include water, air, and compatible fluid service lines where the 1\/2 inch NPT connection integrates with standard pipe configurations. The Cv rating of 4.0 supports adequate flow in moderate-pressure systems operating below 40 psi. The maximum operating temperature is 185 degrees F, supporting use in a range of process and mechanical service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNormally closed (NC) unactuated state — valve shuts off flow when de-energized\u003c\/li\u003e\n\u003cli\u003eBrass body construction for corrosion resistance in water and compatible fluid service\u003c\/li\u003e\n\u003cli\u003eNBR seal material rated up to 185 degrees F\u003c\/li\u003e\n\u003cli\u003eMulti-voltage coil compatibility: 12V DC, 24V DC, 24\/60V AC, 120V DC, 120\/60 to 110\/50V AC, 240\/60 to 220\/50V AC\u003c\/li\u003e\n\u003cli\u003eCv rating of 4.0 for reliable flow performance at moderate pressures\u003c\/li\u003e\n\u003cli\u003eZero minimum operating pressure differential — suitable for gravity-feed and low-pressure systems\u003c\/li\u003e\n\u003cli\u003eCSA Certified, UL Listed, and NEMA 4X rated for wet and washdown environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style or replacement solenoid valve for systems utilizing a 1\/2 inch NPT connection with normally closed operation.

Shut off the fluid supply and relieve system pressure completely before removing or installing the valve. Ensure the selected coil voltage matches the control circuit before energizing. The NEMA 4X enclosure rating permits installation in wet locations, but verify that all conduit entries and fittings are properly sealed to maintain the enclosure rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnactuated State\u003c\/strong\u003e: Normally Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 4.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 40 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Pressure Differential\u003c\/strong\u003e: 0 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Options\u003c\/strong\u003e: 12V DC, 24V DC, 24\/60V AC, 120V DC, 120\/60 to 110\/50V AC, 240\/60 to 220\/50V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 185 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: NBR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3.78 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.76 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Included\u003c\/strong\u003e: Yes (integrated coil required for complete valve)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CSA Certified, UL Listed, NEMA 4X\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72218BN4UN00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538952454450,"sku":"72218BN4UN00","price":379.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8116a96af526ceda7e29fd9bb868fd5c.jpg?v=1785830710","url":"https:\/\/voomisupply.com\/products\/parker-72218bn4un00-solenoid-valve-1-2-inch-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
