Check Valves
Prince Wafer Swing 809 300# Wafer

 

Piping requirements are minimized with the Prince special light weight wafer body style.

Disc closure is assisted with the internal spring.

The disc will never become separated from the body and flow downstream due to our unique disc/stem connection that makes the disc an integrated part of the valve.

Maintenance is easy with the Prince Check Valve's fully field replaceable seat. For critical applications, every rugged ANSI 300# Figure 809 is fully tested.
