    ALC® Wafer Check Valves

    (116)

    The ALC® Check Valve is a non-slam spring-assisted, center-guided "wafer" check valve 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 ALC® Check Valve is an easy-to-maintain check valve for applications involving liquids, gases, or steam. Can be used in horizontal or vertical installation. 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"
    • API 594 Face-to-Face dimensions
    • RF Wafer ends
    • ASME Class 150 and 300
    • Horizontal or vertical installation
    • Standard body materials:
      • A216 Grade WCB carbon steel
      • A351 CF8M stainless steel
    • Stainless steel seat, disc & bushing
    • Spring-assisted silent closing

  • FBC® Insert Wafer Check Valves

    FBC® Insert Wafer Check Valves

    (32)

    The FBC® Check Valve is a compact, lightweight, insert wafer check valve that easily installs between two flanges. The non-slam, spring-assisted design prevents "water hammer" and "reverse flow". The FBC® Check Valve contains all the proven features of the Basic-Check® valve developed originally by DFT® and still in use after 70 years. Like the Basic-Check® Valve, the metal-to-metal sealing area of the disc and seat is precision lapped, providing tight shutoff for applications involving liquids, gases, or steam. Resilient soft seats are available for applications requiring bubble-tight shutoff.

    Standard Features:

    • Sizes 1" thru 4"
    • ASME/ANSI Class 150 and 300
    • Stainless steel seat, disc, guard, retaining ring & spring
    • Extended tag for easy identification of the installed valve
    • Use in Schedule 40 or Schedule 80 pipe
    • Horizontal or Vertical installations
    • Meets ASME B16.34 & MSS SP-126
    • Flange finish per MSS SP-6
    • Spring-assisted silent closing

  • WLC® Cast Iron Body Check Valves

    WLC® Cast Iron Body Check Valves

    (20)

    The DFT® Model WLC Cast Iron Wafer style Silent Check Valve is a spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations. This check valve is cast iron and face-to-face according to MSS-SP126. The joint between the seat ring and body is sealed by the flange gasket upon installation preventing any leakage through the joint when the valve is in service.

    The WLC® Cast Iron Check Valve is ideally suited for applications in water treatment, power generation, and other industries, though not recommended for gas or steam service. It will help to eliminate water hammer caused by double-door style check valves.

    TLW® Wafer Check Valves

    (70)

    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).
