Valve Position Monitoring - Open Solutions for Ease of Mounting

Pepperl+Fuchs: The latest generation of dual sensors from Pepperl+Fuchs monitors the valve position of valve actuators in a reliable and contactless process. These valve actuators are primarily used to achieve rotary movements in fittings, valves, and flaps in industrial applications. 

The valve position is detected using inductive dual sensors. As no mechanical contact is required, the sensor can be separated from the actuator secured on the drive shaft and hermetically sealed. The electronic solution combines a high degree of switching accuracy and well-defined hysteresis with high levels of robustness. To ensure that the sensor can be seamlessly connected to existing control systems within the plant, options with all common types of connection and interface are available.

The valve position display is clearly visible from a distance and offers on-site plant operators all important information at a glance.

The housing material used on the F31K2 is ideal for outdoor use. It provides a high level of UV protection and can withstand extreme temperatures, salt water, and corrosion. The housing is made of robust, translucent plastic and integrates the LED lamps for indicating the power supply, sensor, and valve position. Due to the large terminal compartment and plug-in terminal block, rigid or thick cables pose no problem during assembly, even in hard-to-reach areas.

The F31K2 inductive dual sensor is part of the Pepperl+Fuchs concept of open solutions for providing valve position feedback for valve actuators.  The sensor is mounted directly on the valve actuator; the actuator itself simply needs to be mounted onto the drive shaft by means of a screw, depending on the valve position. All diameters up to 90 mm are covered by just two sizes of actuator - no additional mounting sets are required.

At a glance:

• Robust, impermeable, and durable sensor solution
• Noncontact and therefore permanently wear-free operation
• Compact solution with terminal compartment
• Installation with no additional mechanical mounting aids
• Highly visible valve position display
