产品信息High performance proportional actuator with fail-safe extending function – 2500 N
High performance proportional actuators with fail-safe extending and 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 featuresEasy commissioning
Automatic measurement and adaptation to the valve lift as well as load-dependent end position switch-off helps to reduce commissioning time and protect the valve and actuator from overloading.
Easy troubleshootingProtected hand drive for a safe manual operation enables easy troubleshooting.
Ease of service
The actuator housing cover is easy to remove. Parameters can easily be changed on site - without using a Laptop.
