Compare
​​​​​​​ Motorized proportional and three-point actuators EMO 1 and EMO 3 are designed to be mounted on thermostatic valve bodies, and some of IMI TA control valves, and are installed in heating, ventilation, and air conditioning systems in conjunction with corresponding controllers, e.g. Thermostat E. Even with strict requirements for precision or with process controlled systems with high severity, optimal results can be achieved.
