The Halar true union ball valve can operate as a manual valve or be paired with pneumatic or electric actuators. Its design allows for flow and pressure in either direction, and eliminates the stress inherent to a ball secured only at the top. It is constructed of the most corrosive-resistant thermoplastic material available — a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene (CTFE), containing about 80% CTFE. This is the best material for handling high concentrations of sodium hypochlorite and 98+% sulfuric acid. It has good electrical properties and a broad temperature range, from cryogenic to 300°F (150°C). Available in sizes from 0.5 in. to 1.0 in., the valves turn smoothly even in the most difficult applications.
