Function Description
Dorot Series 300 Flow Control Valve ('30-FR') is activated by the pressure of the pipeline. The valve limits
the flow rate in the network to a preset value, regardless of upstream pressure variations. The valve fully
opens when the flow rate drops below the set point.

The valve can be installed in any position, although installation with the bonnet facing up is recommended for ease of maintenance. b. Flow direction should match the engraved arrow on the bonnet. For maintenance considerations, it is recommended that manual isolation valves (gate or butterfly) are installed, both sides with a strainer between the upstream isolation valve and the valve inlet (as shown in the diagram above).
