    AI Overview
    An API 598 lift check valve is a self-acting, non-return valve designed, tested, and inspected according to the American Petroleum Institute’s API 598 standard. It features a disc (often a piston or ball) that lifts to allow flow and seals against backflow using gravity and pressure, usually in horizontal pipelines. These valves are rated for high-pressure, high-velocity services, ensuring strict, bubble-tight, or low-leakage performance, frequently adhering to BS 1868 and ASME B16.34 design standards. 
    Key Features & Specifications 
    • Purpose: Prevents backflow and protects pumps and piping systems.
    • Design: Often features a bolted cover, renewable seat, and guided piston or ball.
    • Materials: Commonly available in ASTM A216 WCB (Carbon Steel), A217 WC6 (Alloy Steel), and A352 LCB (Low Temp Steel).
    • Size/Class Range: Typically ranges from NPS
      1
      /2
       to 12 (DN20-DN300) and Pressure Class 150 to 900+.
    • End Connections: Available as Flanged (RF), Butt-welded, or Threaded. 
    API 598 Testing & Inspection
    Valves are subjected to rigorous testing to ensure performance: 
    • Shell Test: 1.5 times the pressure rating at
      100∘F100 raised to the composed with power F
      100∘F
       (
      38∘C38 raised to the composed with power C
      38∘C
      ) for 15–30 seconds.
    • Seat Test: High-pressure closure tests to check for leakage, with specific allowable leakage rates defined for hard-seated or soft-seated valves.
    • Documentation: Often supplied with MTRs (Material Test Reports) and pressure test reports. 
    These valves are widely used in petroleum, chemical, fertilizer, and power industries, note API 598 manufacturers and suppliers.

    What is the function of lift check valve?
    The use of a lift check valve is to prevent back circulate a stream. The valve is used especially in water applications because of its layout. The stress of the media is what's used to open the lift check valve, which begins off in a commonly closed (NC) function.Jun 4, 2020

    How to know if a check valve is bad in an air lift?
    Do this test first!!
    1. Let your unit pump up.
    2. Turn it off.
    3. Find the supply line from the pump to the tank.
    4. Remove the supply line from the pump head.
    5. If you hear air coming from the tank you have a bad check valve.
    6. If you do not hear air coming from the tank, then you have a leaky pressure switch.
