Page 3: Designed Use
Argus Designed Use Maintenance Designed Use Ball valves are maintenance-free. It is advisable, however, to actuate them at least once or twice a year. Series EK, FK and HK ball valves are used as shut-off devices in pipelines associated with processing, Safety Information handling and transporting liquid or gaseous as well as solid materials. - Page 4 Argus Safety Information Danger! Caution! De-pressurize the ball valve by turning the ball at 90° before removing drain and ventilation plug Use temperature measuring strips to check that the temperature does not rise beyond the (see Chapter Drain Plug). permissible limits (100°C). The strips must be fitted to the connection near the soft inserts (see Chapter Installing the Welding Connection).
