Valves for the industry Globe valves ■ Gate valves ■ Swing check valves ■

Industrial valves made by company Stahl-Armaturen PERSTA GmbH are designed according to DIN-Standards, EN-Standards and according to the technical rules like AD and the European Pressure Vessel Guideline 97/23/EG. Design, manufacture and testing of these valves was carried out on condition that the valves are operated under normal operating conditions. Normal operating conditions contain for example the following: ■ Operation with liquid or gaseous media, without special corrosive, chemical or abrasive influences. Frequency of temperature-change of app. 3 – 6 °C per minute. Usual flow...
