It features a 3\/8-inch port size, a brass body, and an NBR (Buna-N) elastomer seal. The valve is normally closed in its unactuated state, meaning flow is blocked until a compatible coil is energized. Note that this part requires a separately purchased integrated coil for complete, operational valve assembly. The Cv factor of 2.1 and a 3\/8-inch orifice size are suited for moderate-flow control circuits. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis valve body is appropriate for use in residential and light commercial systems where normally closed fluid shutoff is required, such as refrigerant liquid line control, water supply shutoff, or process fluid regulation. The NBR seal material is compatible with water, many refrigerants, and a range of petroleum-based fluids. Maximum operating temperature is 185 degrees F. Minimum operating pressure differential is 10 psi. Applications include chilled water systems, hydronic control loops, and refrigeration circuits where a solenoid-actuated normally closed valve is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNormally closed (NC) unactuated state — flow blocked without coil energization\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for corrosion resistance in water and refrigerant service\u003c\/li\u003e\n  \u003cli\u003eNBR seal material compatible with water, petroleum fluids, and common refrigerants\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch port with Cv of 2.1 for moderate-flow control circuits\u003c\/li\u003e\n  \u003cli\u003eRequires a separately sourced integrated coil — valve body only as shipped\u003c\/li\u003e\n  \u003cli\u003eRated to 185 degrees F maximum operating temperature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation valve body for systems requiring a normally closed 3\/8-inch brass solenoid valve with NBR seals.

Shut off all upstream fluid supply and relieve system pressure before removing or installing any valve component. Do not energize the coil until all fittings are secure and the system has been leak-checked. Verify that the coil voltage matches the control circuit before completing electrical connections; consult NEC guidelines for low-voltage or line-voltage wiring as applicable.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Factor (NC)\u003c\/strong\u003e: 2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnactuated State\u003c\/strong\u003e: Normally Closed\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 (Buna-N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 185 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Pressure Differential\u003c\/strong\u003e: 10 psi\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73312BN3RNJ0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541918187826,"sku":"73312BN3RNJ0","price":832.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f9b738ab933d9f24e5c35cbbdefa7c7_18dc53f5-873f-4eb5-b0d9-e0545f9c43e4.jpg?v=1785887770","url":"https:\/\/voomisupply.com\/products\/parker-73312bn3rnj0-solenoid-valve-3-8-in-brass-nbr-nc","provider":"Voomi Supply","version":"1.0","type":"link"}
