Performance Feature:

1. Economical Design: Low weight and short laying length produce savings in initial cost, space requirements, and installation when compared to full-body, swing type check valves
2. Minimal Head Loss: Head loss is minimized by providing a short, straight and virtually unobstructed flow path.
3. The spring-loaded disc is designed with very low cracking pressure which reduces the amount of energy required to open the valve
4. Quick Closure to Reduce Water Hammer: Shut-off is achieve via the fully automatic, spring assisted disc that closes near zero flow velocity – the lightweight, sing disc design creates a positive shutoff prior to flow reversal which helps keep surges to a minimum
5. Duration & High-Quality Design: The single check valve has a carbon steel body which allows it to perform well in higher temperature applications – units are epoxy painted
