Commonly installed in steam systems, refinery equipment, power generation facilities, chemical processing plants, and oil and gas infrastructure where dependable backflow prevention is required, this forged steel valve protects pumps, compressors, and process equipment from reverse pressure conditions. Maintenance teams, OEM engineers, and system integrators use the S74 for piping system repairs, facility upgrades, retrofit projects, and replacement of worn or failed check valves. Vogt Class 800 forged check valves are widely used in critical service applications due to their robust construction and pressure handling capabilities. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"914\" data-end=\"931\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"932\" data-end=\"1462\"\u003eThe Vogt Flowserve S74 check valve is commonly used in industrial environments including steam distribution systems, boiler feedwater lines, refinery process units, petrochemical plants, power generation facilities, and industrial utility systems where reliable backflow prevention and high-pressure service performance are essential. The Class 800 pressure rating makes it particularly suitable for high-pressure piping applications involving steam, condensate, oil, gas, and process fluids.\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1464\" data-end=\"1493\" class=\"PDq2pG_selectionAnchorContainer\"\u003eTechnical Specifications:\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp data-start=\"1494\" data-end=\"2440\"\u003e• Brand: Vogt Flowserve\u003cbr data-start=\"1517\" data-end=\"1520\"\u003e• Manufacturer Part Number (MPN): S74\u003cbr data-start=\"1557\" data-end=\"1560\"\u003e• Product Type: Forged Steel Check Valve\u003cbr data-start=\"1600\" data-end=\"1603\"\u003e• System: Industrial Fluid Handling and Process Piping System\u003cbr data-start=\"1664\" data-end=\"1667\"\u003e• Valve Type: Check Valve\u003cbr data-start=\"1692\" data-end=\"1695\"\u003e• Valve Size: 3\/4 Inch\u003cbr data-start=\"1717\" data-end=\"1720\"\u003e• Pressure Class: Class 800\u003cbr data-start=\"1747\" data-end=\"1750\"\u003e• Function: Prevents reverse flow in pressurized piping systems\u003cbr data-start=\"1813\" data-end=\"1816\"\u003e• Flow Direction: One-Way Flow\u003cbr data-start=\"1846\" data-end=\"1849\"\u003e• Body Construction: Forged Steel\u003cbr data-start=\"1882\" data-end=\"1885\"\u003e• Seat Type: Integral Seat\u003cbr data-start=\"1911\" data-end=\"1914\"\u003e• Bonnet Type: Bolted Bonnet\u003cbr data-start=\"1942\" data-end=\"1945\"\u003e• Gasket Type: Spiral Wound Gasket\u003cbr data-start=\"1979\" data-end=\"1982\"\u003e• Valve Design: Piston Check \/ Ball Check Configuration\u003cbr data-start=\"2037\" data-end=\"2040\"\u003e• Connection Type: Threaded or Socket Weld (configuration dependent)\u003cbr data-start=\"2108\" data-end=\"2111\"\u003e• Standards Compliance: ASME B16.34, API 602\u003cbr data-start=\"2155\" data-end=\"2158\"\u003e• Application Media: Steam, Water, Oil, Gas, and Process Fluids\u003cbr data-start=\"2221\" data-end=\"2224\"\u003e• Application Environment: Power Generation, Refining, Petrochemical, and Industrial Processing\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2442\" data-end=\"2466\" class=\"PDq2pG_selectionAnchorContainer\"\u003eCommon Replacements:\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp data-start=\"2467\" data-end=\"2602\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Vogt Class 800 Forged Steel Check Valve\u003cbr data-start=\"2508\" data-end=\"2511\"\u003e• Crane Powell 3\/4\" Class 800 Check Valve\u003cbr data-start=\"2552\" data-end=\"2555\"\u003e• Velan 3\/4\" Class 800 Forged Steel Check Valve\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"New","offer_id":51714378039598,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9fc2553e-28d9-448e-ae34-377302eb7061.jpg?v=1770424672","url":"https:\/\/plgautomation.com\/products\/flowserve-vogt-s74-3-4-800-check-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
