The valve features a stainless steel ball and stem for corrosion resistance and long service life. Rated at 200 CWP (cold working pressure), it is built to handle demanding fluid control applications. A lever handle is included for manual quarter-turn operation. Licensed plumbers and pipefitters are the typical installers for this class of flanged valve.\u003c\/p\u003e\n\u003cp\u003eThis valve is suited for commercial and industrial plumbing, HVAC hydronic systems, and process piping applications where a 4-inch flanged connection is specified. The full port design delivers unrestricted flow with minimal pressure drop, making it appropriate for systems where flow efficiency is a priority. The cast iron body provides durability in above-ground and inline installations across a wide range of compatible fluid services.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull port ball design minimizes pressure drop and flow restriction\u003c\/li\u003e\n  \u003cli\u003eStainless steel ball and stem resist corrosion in demanding service environments\u003c\/li\u003e\n  \u003cli\u003eCast iron body provides structural durability for commercial and industrial use\u003c\/li\u003e\n  \u003cli\u003eFlanged end connections for secure, leak-resistant inline installation\u003c\/li\u003e\n  \u003cli\u003eRated at 200 CWP for reliable performance under cold working pressure conditions\u003c\/li\u003e\n  \u003cli\u003eLever handle included for quick quarter-turn manual operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation ball valve for 4-inch flanged piping systems in commercial plumbing and hydronic applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the ASME B16 flange standards. Shut off and depressurize the system completely before removing or installing the valve. Inspect flange gaskets and bolting hardware for proper seating and torque per the flange specification — do not rely on valve-body specs alone for joint integrity. Verify flow direction and handle orientation before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Type\u003c\/strong\u003e: Full Port\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCold Working Pressure (CWP)\u003c\/strong\u003e: 200 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall and Stem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 88.70 pounds\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: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 820975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51233518584114,"sku":"0820975","price":894.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307634023.jpg?v=1780102037","url":"https:\/\/voomisupply.com\/products\/watts-820975-flanged-cast-iron-ball-valve-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
