Special Note

All standard DSR 500 Positioners are programmed for fail-safe to close logic. These standard units can be reprogrammed by GF Piping Systems for fail-safe to open logic with special request. DSR 500 units can be built and programmed specifically for double acting logic with special request but this requires additional internal components, therefore all air-spring units cannot be converted to a double acting unit in the field .


Sample Specification

The DSR-500 shall be an electro-pneumatic positioner with
versions suitable for both rotary and linear strokes. The
housing shall be polyamide with a KTL-coated Aluminum base
plate. The input signal shall be either 4-20mA or 0-10V and
manually spanned with the aide of push buttons on the positioner’s display board.
