History

The Emech electronic actuator has evolved over 5 years of intensive research, engineering design and field testing. After initial prototype trials, the first generation Emech Actuator was installed in a large dairy processing facility in September 2000, with further unit installations in pharmaceutical manufacturing facilities in 2001.

Further enhancements were added, and in 2002 the Generation Two model evolved, including an aluminium fin casing to dissipate heat, a lockable manual override lever for emergency positioning, a user friendly control panel and software configuration improvements.

In June 2003, Emech designed further enhancements and a third generation actuator was launched improving calibration accuracy and programmable software that can be installed via the internet.


The Benefits

Emech actuators offer intelligent control. They provide the ability to sense at the source, and provide reliable control, either in an independent standalone environment, or as an integral part in PLC plant systems.

Depending on the application, butterfly and rotational valve control can be significantly enhanced by the installation of an Emech actuator.

Emech G1 actuators provide compact high-speed actuation solutions for 0° to 350° applications up to 100 Nm ( 885 in.lb ).
