TA-MC55Y, TA-MC55

High performance proportional actuators with automatic stroke adaptation which provide accurate modulating, 3-point or on/off control when used together with combined control and balancing valves – both with or without integrated Δp controller – as well as stand-alone 2-way and 3-way control valves from IMI Hydronic Engineering.

Product Information

High performance proportional actuator – 135 lbf (600 N)

High performance proportional actuators with automatic stroke adaptation which provide accurate modulating, 3-point or on/off control when used together with combined control and balancing valves – both with or without integrated Δp controller – as well as stand-alone 2-way and 3-way control valves from IMI Hydronic Engineering.

Key features

Easy commissioning

Automatic measurement and adaptation to the valve lift as well as load-dependent end position switch-off which helps to reduce commissioning time and protect the valve and actuator from overloading.

Easy troubleshooting

Protected hand drive for a safe manual operation which enables easy troubleshooting.

Ease of service

The actuator housing cover is easy to remove (without screws). Parameters can be easily changed on site without using a Laptop.
