Our AVAMO ASG Direct Gas actuators are designed to directly use the existing pipeline pressure and work with natural sweet and sour gas. The ASG is based on our field-proven scotch-yoke actuators and adapted to its unique working environment. Its design ensures optimal performance to operate ball, butterfly and plug valves even in the harshest environmental conditions.
The actuator is designed for longevity, ensured by bronze slide blocks and nickel or Ionit Ox plated cylinders. Chromium plated rods and custom paint jobs provide an excellent protection against corrosion.
AVAMO ASG actuators have a modular design and can be equipped with several options. The actuator is available as single- or double acting version and can be used for on/off or modulating applications. NTF also applies a spring cylinder for emergency-shut-down-applications if necessary. The cylinder can be fitted on both sides of the actuator to either create a fail-close or fail-open configuration.
