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 Gate Valves are widely used ON/OFF valves for large diameter, full-port applications. When the valve is fully open, it allows straight-through passage through an opening that is essentially the same size as the inside diameter of the connecting pipe. Asahi/America Gate Valves are traditionally used for ON/OFF service, but because of the unique sliding plug design, which provides a larger seating area than conventional gate valves, it can be used in throttling applications. Asahi/America Gate Valves feature two different designs of plugs, one with a solid polypropylene plug and the other with a resilient elastomer plug. Each valve is specifically designed to handle unique corrosive applications.
