Valves & Actuation

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

Asahi/America Duo-Bloc® Type 21 thermoplastic ball valves provide a dependable and economical way to handle corrosive chemicals. They perform at temperatures up to 250°F, and pressures to 230 psi (150 psi for polypropylene valves). True Union Duo-Bloc® Type 21 Ball Valves can be lifted from the line, simply by loosening the two union nuts. The valve can be disassembled, and parts may be replaced. The Duo-Bloc® feature blocks in two directions, leaving full pressure opposite, and allowing disconnection of downstream piping.
