Valves & Actuation
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.
This heavy-bodied, quarter-turn shut-off valve is popular where maintenance-free installations are desired for a variety of chemical, industrial and OEM applications. Factory adjusted sealed units are available in IPS sizes 1/2" through 6", with choice of either socket or threaded end connectors. Spears PTFE floating seat design reduces seat wear for extended valve life, smooth operation, bubble-tight shutoff. 100% factory tested. Safe-T-Shear® Stem to help prevent leaks out in the event of stem damage. 235 psi @ 73°F (for complete size range).
