Industrial Automation | DC
— ifm’s innovative MVQ smart valve sensor continuously monitors the precise position of the valve. It not only detects if the valve is open or closed but also provides immediate warnings about closing position drift. By providing this real-time information, valve failure issues can be corrected immediately, preventing critical process contamination or unexpected downtime.

IFM MVQ101/201 Series Valve Position Sensor

Technical Features

Provides real-time feedback on quarter-turn valve position, warns of operational changes, and prevents unexpected downtime.

Easily set switch points via the teach button.

Digitally transmit valve position parameters.

Provides diagnostic functions such as seal monitoring and deposit interference detection.

Bright LEDs are visible from all angles to indicate open, closed, or alarm status.

Employs advanced magnetic technology to detect the actual valve position with an accuracy of within 0.1 degrees.

Feature	Typical Switch Box	MVQ Smart Valve Sensor
Service Life	The switch box uses limit switches that may contact a cam to indicate valve position. These mechanical switches have moving parts that can potentially stick, break, or wear out.	The sensing technology has no moving parts that can wear out or break. Due to the non-contact operation, this sensor has a longer service life in the application.
Valve Position Feedback	Only provides 2 valve position feedbacks: open and closed.	The smart valve sensor monitors the precise movement of the valve and can indicate: valve open, valve closed, and warning.
Diagnostic Function	None.	Indicates via IO-Link: Valve not completely closed Valve seal damaged Valve movement obstructed
Dimensions	The switch box is tall and bulky, leaving only limited installation space for the valve.	The MVQ uses a compact design, with dimensions that are only a quarter of the switch box, thus saving valuable installation space.
Cost-Effectiveness	Typically, high long-term ownership costs due to annual replacement costs, shutdown maintenance costs, and preventive maintenance labor fees.	Because the sensor is solid-state and includes predictive valve diagnostics, it can reduce spare parts inventory, with savings far exceeding the $252 purchase price.

Benefits Introduce In Detail

Smart Valve Sensor Indicates Early Signs of Failure in Industrial Quarter-Turn Valves

New! Most feedback devices only indicate two positions of a quarter-turn valve: open and closed. But what happens if the feedback shows “closed” when the valve is not actually closed? Does this mean the valve is about to fail?

ifm’s innovative MVQ smart valve sensor continuously monitors the precise position of the valve. It not only detects if the valve is open or closed but also provides immediate warnings about closing position drift. By providing this real-time information, valve failure issues can be corrected immediately, preventing critical process contamination or unexpected downtime.

Flexible Configuration and Diagnostic Functions

ifm’s MVQ smart valve sensor provides real-time predictive information, which can increase production output to improve operational performance, setting a whole new benchmark for cost-effectiveness.

The open and closed setpoints can be easily established using the buttons on top of the sensor, or setpoints for early diagnosis of valve failure can be configured via IO-Link.

IO-Link provides self-diagnostic functions, which can reduce periodic maintenance requirements. Preventive measures can be set, such as seal monitoring (when the valve exceeds its closed position) or deposit monitoring (when the valve does not completely close). Additionally, the valve’s opening and closing times can be monitored to determine if it is operating correctly.
