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 with Filters and Pressure Regulators
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.
