Quarter-turn and rising stem valves are used for process control in industrial automation and food and beverage applications. Typical applications include tank farms, diverter valves, valve skids and valve banks.
Traditional valve position feedback solutions can include large switchboxes. These high-maintenance packages are mounted on top of the actuator and use mechanical devices and cams to indicate valve position. Since the mechanical arm must make physical contact with the cam, it can stick, bounce or break. If the switchbox fills with water, other problems can occur including corrosion, loss of signal and short circuits.
ifm’s solutions work on a non-contact sensing principle and because there are no moving parts, they are less likely to become misaligned, wear out or break. These products are also completely sealed, so water ingress cannot occur.
