A new TÜV certificate has confirmed that Pennsylvania-based AUMA’s electric actuators have passed demanding corrosion protection tests and meet the requirements of EN ISO 12944-6 for corrosivity categories C5-M long (marine, coastal and offshore areas) and C5-I long (industrial areas with high humidity and aggressive atmospheres).
“Our actuators are often installed in very harsh environments, especially in tank farms or on offshore platforms. Excellent corrosion protection is therefore a key concern for us as an actuator manufacturer,” says Gert Wetzel, Product Manager at AUMA.
Key to the corrosion resistance is a two-layer powder coating. The coating is designed to remain intact even if the actuator is removed from the valve or if the housing is opened during installation or commissioning
