$Asahi/America Ball Check Valves: Automatic - CPVC \ EPDM$

Horizontal or Vertical Operation
Asahi/America Ball Check Valves employ a free-moving ball which unseats to permit flow in one direction, but seals against a seat to prevent backflow. They may be installed in either vertical or horizontal pipe runs. These ball check valves are rated for 150 psi @ 120°F in the PVC version.

True Union Design - 1/2" through 2"
Asahi/America Ball Check Valves (1/2" through 2" sizes) can be lifted from the line without having to move the piping, simply by loosening the two union nuts. The 3" and 4" versions are manufactured with a space-saving single union design.

Features
• Uniseat / seal of EPDM or FKM • Good flow characteristics • Minimum shut-off pressure of 5 psi • Rated for full vacuum • Mount vertically or horizontally

Options
• Teflon-coated FKM uniseat/seal • Solid thermoplastic ball • Spring-loaded ball to assist ball in seating faster • Foot valve screen assembly
