Engineered and Flow Tested for Superior Performance
Designed for quick, positive seal-off with minimum turbulence, low restriction and maximum fluid transfer, this industrial-grade ball check valve is used in a wide variety of industrial and chemical processing applications.
Heavy-Bodied PVC or CPVC Construction
Spears True Union Ball Check Valves never rust, scale or pit, providing exceptional chemical and corrosion resistance. Strong buttress-type threads on the union nuts allow higher pressure-handling capability and quick in-line installation and servicing.

  • Spears computer-engineered design provides superior fluid flow with minimum turbulence. Eliminates “chatter” often encountered in ball check valves.
  • Maximum Internal Pressure of 235 psi at 73°F for the most demanding applications of 1/2" - 4" valves.
  • All Spears True Union Ball Check Valves are NSF Certified for potable water use.
