Find My Check Valve
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).
