Screwed Swing Check Valves: Compact Gravity Flow Protection

Screwed swing check valves are the primary choice for small-to-medium pipe configurations requiring high flow capacity and automatic backflow prevention. Featuring female threaded ends (BSP or NPT), these valves screw directly onto the pipework, eliminating the need for bulky flanges or specialized installation tools.

Because the internal disc swings completely clear of the media path under forward pressure, screwed swing check valves maintain a full-bore flow path that minimizes pressure loss across compact utility lines.

  • Best Used For: Residential plumbing, commercial heating loops, booster pump inlets, and low-pressure compressed air or condensate lines.
  • Key Body Types: Typically available in a standard Y-pattern or horizontal pattern, often featuring a top access cap that allows the disc and seat to be inspected or cleaned without removing the valve body from the pipework.
  • Installation Rule: Must be installed in horizontal lines, or vertical lines with a strict upward flow, to allow gravity to properly reseat the disc.
