Functional description

The intended use of the Pressure regulator U42 F is pressure relief of a gas from an inlet pressure to a fixed or adjustable outlet pressure.

Pressure reduction is performed by the pressure regulator. It is optionally equipped with one pressure gauge to display the inlet pressure and the outlet pressure. The outlet pressure is set to the desired value by turning the of the handwheel on the pilot pressure regulator and is not permitted to exceed a defined maximum value given on the label.

Pressure adjustment via the pilot pressure regulator is done with external medium (pilot gas). To reduce the outlet pressure, the venting valve must be opened briefly to discharge the excess pressure.

In the case of the single-stage pressure regulation present here, the set outlet pressure does not remain completely constant and instead rises slightly as the inlet pressure decreases (e.g. caused by a draining cylinder).
