41N-E1N-SF Series
Series 40N / 41N Valve Positioner
Series 40N / 41N
Improving Control Through
Advanced Technology
Moniteur’s Series 40N /41N pneumatic (3-15psi) and electro-pneumatic (4-20mA) valve positioners are advanced control devices which provide unparalleled stability in difficult environments.
In virtually any application, this positioner’s performance is improved compared with typical “spool valve” type designs.
Just check the features listed below:
Features & Benefits – 40/41 Positioner
Unique Magnetic Torque Motor 4-20 mA I/P automatically compensates for supply pressure, atmospheric pressure and ambient temperature changes, and is unaffected by EMF. The vibration resistant design has no resonance effects from 5-200Hz. In real life, the perfromance and sensitivity are clearly superior to standard valve positioner designs.
Reduced Bleed Pilot Valve reduces air consumption by more than 50% No Spool Valves are used for air delivery, improving resistance to dirty plant air
Rugged Aluminum Housing with a triple corrosion-resistant interior and exterior coating stands up to harsh environments
Precise Calibration with simple SPAN and ZERO adjustments.
Precision Zero-Hysteresis Coupling System for NAMUR actuators provides superior accuracy and repeatability by eliminating “slop”.
Stainless Steel Gauges Standard
Optional Limit Switches and 4-20mA Feedback
Each Valve Positoner Performance Tested – Test results included in the box with each positioner guarantee consistent performance.
