True Union

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.

GF Type 546 True Union Ball Valves feature a short overall length, buttress thread design and universal multi-function module. This module significantly expands the number of uses for the Type 546 by allowing the user to easily add different accessories, actuators and switches. The multi-function module can also be used for easy wall and panel mount installation or as a position feedback unit by adding one of five different micro-switch options. GF Type 546 valves are easily automated with the newly introduced line of pneumatic and electric actuators that have been specifically designed to compliment the modularity and flexibility of the Type 546 ball valve.
