Bürkert 8792 Positioner and 8793 Positioner-Process Controller digital positioners

Bürkert’s digital positioners have zero air bleed and consumption at rest, drawing air only when the pneumatic device moves.

Traditional positioners bleed high air volumes, with one positioner reporting 540 L/h consumption at low pilot-pressure. The zero-bleed positioners are said to reduce compressed air use dramatically, saving money and power and promoting ecofriendly processing.

The Types 8792 Positioner and 8793 Positioner-Process Controller suit rotary and linear process valves, as well as virtually any pneumatically controlled instrument including valves, cylinders and dampers. The positioners are available for direct or remote mount, all with IP65/67 housings for robust service in challenging environments.

Using the company’s piloting technology to deliver high precision, the digital positioners are able to control to up to 150 L/min for both spring return and double-acting actuators. This represents a significant jump on traditional positioner flow rates, giving far wider scope of use.
