Check Valves
![Spears Ball Check Valves: Automatic - CPVC \ FKM](/sites/default/files/styles/list/public/images/product/92ebda45e6d6fd3e0b9054b4784e/Spear_2000_Check_CPVC.gif?itok=vTVfjb3A)
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.

PVC Utility Swing Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second.
• Pressure Rating - 150 psi @ 73°F • Maximum Service Temperature - 140°F • EPDM seal for positive sealing
• Flow velocity < 5 ft./sec.
