Device that delivers a predefined and constant pressure value "downstream" (within the foreseen operating limits) as the inlet pressure and/or flow rate varies. The compensated obturator ensures precision in regulating the outlet pressure even in the case of high and sudden variations in the inlet pressure.
It is equipped with:
- spring for regulating outlet pressure;
- security membrane;
- outlet pressure point (with some exceptions) for outlet pressure control. On some models, the pressure point is also present on the inlet;
It can also be supplied with a built-in filter element (FRG/2M models).
Available 90° connections for threaded connections from DN 15 to DN 50.
Reference standards: EN 88-1 – EN 13611.
