    A216 WCB Check Valve - Relia Valve
    WCB check valves are industrial cast carbon steel (ASTM A216 WCB) valves designed to prevent backflow in high-temperature, high-pressure, or general-purpose piping systems (oil, gas, steam). They feature robust construction, such as swing or ball designs, offering durability and reliable sealing. Common options include flanged connections (e.g., ANSI 150#). 
    Key Features of WCB Check Valves 
    • Material: ASTM A216 WCB (Grade B cast carbon steel) is suitable for high-temperature service up to roughly
      900∘
      F
      .
    • Types: Available in swing check designs (utilizing a flapper to prevent backflow) and ball check designs (using a ball to seal).
    • Applications: Ideal for petrochemical, steam, water, and oil applications.
    • Performance: WCB provides good ductility, with at least 22% elongation.
    • Structure: Common top-entry access allows for easier in-field maintenance. 
    WCB Check Valve Components 
    • Body: ASTM A216 WCB.
    • Trim: Often includes stainless steel or 13Cr to ensure durable seating.
    • Installation: Installed horizontally or vertically (upward flow). 
    Limitations 
    • Temperature: Not suitable for very low-temperature service as they may become brittle.
    • Corrosion: WCB is less resistant to harsh corrosive environments compared to stainless steel. 
    • Swing check valve flanged steel WCB A216 TRIM.8-ANSI150#
      Model: Swing check valve, Material body: Steel ASTM A216 WCB. Connection: Flange RF ANSI 150#, Material disc: ASTM A216 WCB+13Cr.
