Bürkert releases digital positioners

Bürkert has released a new series of digital positioners for process control applications.

Including zero air bleed at rest position, the Type 8791 Basic Positioner, 8792 Positioner and Type 8793 Positioner with integral Process Controller are for use with quarter turn and linear process valves, as well as pneumatically controlled instrument such as valves, cylinders and dampers.

The positioners are available as direct mount or remote versions.

The digital positioners have an integrated pilot valve system which uses filtered and recycled air, and is designed for low air use and no air use at the rest position.

It can control up to 150 litres per minute for spring return and double acting actuators.

Automatic positiner tune and process tune features have been included with one minute push buttons.
