The TLW® Check Valve (Tapped Lug Wafer) was engineered for applications where exposed studs are not suitable. This non-slam spring-assisted, center-guided, lugged pattern wafer check valve is designed to prevent water hammer and reverse flow. The lightweight compact design fits between mating flanges and meets API 594 face-to-face dimensions. The TLW® Check Valve body design eliminates potential leak paths to the environment and is an easy-to-maintain check valve for applications involving liquids, gases, or steam. Tapped holes are provided in the body for lifting lugs to assist with installation (10" and larger sizes only).

Standard Features:
  • Sizes 2" thru 24"
  • ASME Class 150 and 300
  • Standard Body Materials:
    • A216 Grade WCB Carbon Steel
    • A351 CF8M Stainless Steel
