Instrumentation & Control Solutions for Industrial Automation

Precision, safety, and reliability for pneumatic, hydraulic, and electro-hydraulic actuation systems.
Engineered for ESD, PSD, on/off, and modulating valve applications.

Complete Instrumentation Packages for Reliable Valve Automation

Nordenflow delivers fully engineered instrumentation and control solutions that ensure stable operation, fast response, and long-term reliability of your valve automation systems.
From solenoid valves and filter regulators to smart positioners and partial stroke testing (PST) modules, every component is selected and configured to guarantee safety performance, compliance, and lifecycle efficiency.
We specialize in high-integrity instrumentation and control solutions that bridge the gap between process logic and final element performance. Our integrated packages are engineered to enhance the safety, reliability, and diagnostic capabilities of automated valve assemblies in critical environments.
Our solutions are designed for industries operating in demanding conditions—LNG, marine, energy, petrochemical, refining, pulp & paper, and general process automation.
All instrumentation packages can be supplied ATEX, SIL2/3, or PED compliant and integrated directly into actuator assemblies or control panels.

Instrumentation Categories

Solenoid Valves & Manifolds

fast and reliable actuation control

Our direct-acting solenoid valves ensure safe and rapid control in pneumatic and hydraulic systems.
They are designed for harsh environments, offering:
– ATEX & SIL-compliant options
– Stainless steel 316L bodies for corrosion resistance
-Low power consumption
– High flow capability for large actuators
– Modular manifolds for multi-valve configurations

Ideal for ESD, blowdown, trip valves, and safety instrumented systems (SIS).

Filter & Pressure Regulators

clean and stable air supply for instrumentation

High-efficiency stainless steel filters and pressure regulators ensure a stable and contamination-free air supply—critical for reliable actuator and positioner performance.
– High-flow designs
– Water/oil removal for extreme temperatures
– environments
– Multiple mounting options
– Compact industrial-grade construction
– High-flow capacity, dome-loaded regulator
Designed for oil & gas, power generation, marine, and general process applications.

Partial Stroke Test & Positioners

advanced monitoring and diagnostics for ESD and modulating valves

Digital positioners and PST devices provide continuous performance monitoring, diagnostic feedback, and partial stroke capabilities for critical valves.
Benefits include:
– Enhanced reliability of emergency shutdown valves
– Verification of valve function without full stroke
– Integration with DCS/SCADA via HART or digital communication, I/P signal conversion, and calibration history
– Safety compliance for SIL2/3 loops
– Support for single-acting and double-acting actuators.
-Diagnostics platform
Essential for high-integrity protection systems (HIPS) and plants with heavy functional safety requirements.

Instrumentation Technologies:
Digital Positioners:
High-resolution modulating control with HART, Foundation Fieldbus, and Profibus integration for real-time valve diagnostics.
Solenoid Control Systems:
High-flow, low-power solenoid valves and custom 316L stainless steel manifolds for reliable fail-safe operation.
PST (Partial Stroke Testing):
Intelligent testing solutions that verify valve availability without process interruption, significantly improving SIL (Safety Integrity Level) performance.
Limit Switches & Feedback:
Robust position monitoring with gold-plated contacts or inductive sensors for explosive atmospheres (ATEX/IECEx).
