WC6 Swing Check Valve: High-Temperature Alloy Steel Non-Return Valve<\/div>\n
<\/div>\n
<\/div>\n
Product Overview<\/strong><\/div>\n
The WC6 Swing Check Valve<\/strong> is a premium industrial non-return valve engineered specifically for high-temperature and high-pressure steam, water, and hydrocarbon pipelines. Cast from durable ASTM A217 Gr. WC6 chrome-moly alloy steel<\/strong>, this valve offers exceptional resistance to thermal creeping, scaling, and hydrogen attack. It serves as an automatic mechanism to prevent pipeline backflow, protecting upstream pumps, boilers, and turbine equipment from devastating fluid shocks.<\/div>\n

Key Technical Features<\/strong><\/div>\n
    \n
  • Chrome-Moly Alloy Superiority:<\/strong> The WC6 composition (1.25% Chromium, 0.5% Molybdenum) ensures high mechanical strength and structural stability at continuous operating temperatures up to 593\u00b0C (1100\u00b0F)<\/strong>.<\/span><\/li>\n
  • Stellite Hardfaced Seating (API Trim 5):<\/strong> The valve disc and seat ring are overlaid with cobalt-based Stellite alloy, providing maximum resistance to high-velocity erosion, abrasive wear, and thermal galling.<\/span><\/li>\n
  • Full-Port Flow Profile:<\/strong> The internal swing disc lifts completely out of the flow path under forward pressure, optimizing flow capacity (high Cv value) and reducing system pressure drop.<\/span><\/li>\n
  • Robust Bolted Bonnet (BB):<\/strong> The heavy-duty bolted bonnet design features a premium pressure-seal or graphite gasket, allowing safe, fast inline maintenance and internal component inspection.<\/span><\/li>\n

    <\/div>\n
    Industry Applications<\/strong><\/div>\n
      \n
    • Power Generation:<\/strong> High-pressure boiler feed-water loops, main steam piping, and turbine extraction lines.<\/span><\/li>\n
    • Petrochemical Refineries:<\/strong> Hydrocracking, catalytic reforming, and high-temperature hydrocarbon processing.<\/span><\/li>\n
    • Chemical Plants:<\/strong> Superheated steam distribution networks and thermal fluid transport lines.<\/span><\/li>\n
    • Oil & Gas Downstream:<\/strong> High-temperature gas processing plants and refining manifolds.<\/span><\/li>\n
