Ball 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.
Manufactured from glass reinforced polypropylene for strength and durability-will never rust or corrode. Self-aligning ball rotates freely against Teflon® seats. Unique body-to-flange design allows for low torque on/off operation. Viton® o-ring stem seal and EPDM o-ring body seal. Available with blue Norwesco handle or blank yellow handle. Pressure rated at 125 PSI @ 70°F. All valves tested by air pressure under water.
This heavy-bodied, quarter-turn shut-off valve is popular where maintenance-free installations are desired for a variety of chemical, industrial and OEM applications. Factory adjusted sealed units are available in IPS sizes 1/2" through 6", with choice of either socket or threaded end connectors. Spears PTFE floating seat design reduces seat wear for extended valve life, smooth operation, bubble-tight shutoff. 100% factory tested. Safe-T-Shear® Stem to help prevent leaks out in the event of stem damage. 235 psi @ 73°F (for complete size range).
Spears® True Union 2000 Ball Valves provide maximum versatility with fully interchangeable (with Series 2000 Ball Check Valves and 3-Way Ball Valves) valve cartridges.
