Valves & Actuation
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.

Asahi/America Type 14 Diaphragm Valves offer many combinations of body materials and elastomeric diaphragm materials. This valve is designed to resist abrasion and clogging. The path of the fluid has a smooth, streamlined flow. Slurries at low pressure that would normally clog most other valve designs easily pass thru this type of valve. Asahi/America Type 14 Diaphragm Valves are ideally suited for throttling as well as ON/OFF service in applications ranging from water treatment to chemical abrasion processes.
