The Econ scotch yoke actuator comes with a heavy duty aluminum housing which can support up to 2.2 million in-lb (250,000 Nm). This actuator produces reliable and dependable automation for quarter turn valves. Engineered and built to withstand most applications and environmental conditions, the precision design and quality of our actuators provide long and safe performance for valve control.

AVAILABLE OPTIONS

Manual Overrides

The manual override is an important requirement for many valve/actuator applications. In case that air fails, the user will be able to open or close the valve manually. Econ has a variety of override options available to meet any requirement. Available options include jackscrew or hydraulic manual override.
