Device that delivers a predefined and constant pressure value "downstream" (within the expected operating limits) as the inlet pressure and/or flow rate varies. The compensated shutter guarantees precision in the regulation of the outlet pressure even in the case of large and sudden variations in the inlet pressure.
It is equipped with:
- spring for regulating the outlet pressure;
- safety membrane;
- outlet pressure tap (with some exceptions) for controlling the outlet pressure. On some models the pressure tap is also present at the inlet;
It can also be supplied with a built-in filter element (FRG/2M models).
90° connections available for threaded connections from DN 15 to DN 50.
