High performance proportional actuator – 225 lbf (1000 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.
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.
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.
For modulating or 3-point control.
