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.
PVC True Union Utility Swing Check Valves are designed for horizontal installations, but may be installed in up-flow vertical position. Check valves must be installed with the valve’s FLOW arrow pointing in the direction of the flow. Flow velocity should not exceed 5 feet per second. Excellent for Pool and Spa, OEM and General Purpose applications.
