The Actuator

The AVAMO ACP compact Scotch Yoke actuator has been developed for both on/off- or modulating-operations and is available as a single- or double-acting version in a compact design. The unique design ensures optimal performance to operate ball, butterfly and plug valves even in the harshest environments.

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 provides an excellent protection against corrosion.

The ACP series can be used for on/off or modulating applications.

It is available in a single- or double acting version and provides forces up to 4.500 Nm of torque.


AVAMO ACP actuators have a modular design and can be equipped with several options. The Scotch-yoke mechanism can be driven by an air or gas cylinder and is either available as a single- or double acting version. NTF also fits a spring inside of the cylinder for emergency-shut-down-applications if necessary. This creates either a fail-close or fail-open configuration.
