Performance Specifications

Flow Characteristics

Equal-percentage flow characteristic according to DIN EN 60534-2-4.

Operating Limits

In addition to the maximum operating pressures, the application range of Bürkert process valves is limited by the nominal pressure in accordance with the relevant standard.

The maximum permissible temperature for the environment and the medium are dependent on each other. The maximum allowable temperature curves of different device variants are shown in the temperature chart.

Product Design and Assembly

The electromotive linear drive consists of a brushless DC motor, a gear and a spindle system that transfers the force to the closing element. The integrated electronics are controlled either by standard signals or via a fieldbus (digital).

Service and Maintenance

Adjusting the Position Control – Running X.TUNE

When the X.TUNE function is run, the position control is adjusted to the physical stroke of the actuating element used.

WARNING

Danger due to uncontrolled process after running the X.TUNE function. If the X.TUNE is run under medium pressure, the controller will be incorrectly adjusted. This will result in an uncontrolled process.

• Never run the X.TUNE under medium pressure.
• Secure system against unintentional activation.
