Industrial Air Preparation Solutions for Reliable Valve Automation
NordenFlow is your authorized Norgren premier partner in Finland, delivering high-performance air preparation solutions centered on the Excelon® Plus modular series. Clean, dry, and stable instrument air is the critical foundation for any reliable pneumatic control loop. Our integrated Filter-Regulator (FRL) units are engineered specifically to protect high-value actuators and smart positioners from the primary causes of failure: moisture carryover and abrasive particulates.
Engineered for Critical Automation Applications
Our filters and regulators protect pneumatic actuators and instrumentation against contaminants, water, pressure instability, and fluctuating supply conditions.
They ensure:
- Consistent actuator response
- Extended equipment lifetime
- Stable control performance
- Compliance with safety instrumented functions (SIF)
Units are available as stand-alone components or complete manifold assemblies with integrated gauges, shut-off valves, and quick-exhaust elements.
