Velocity Check Valves REF-3000 Series
The REF 3000 Series velocity check valve is used to automatically block the flow of the line on which it is installed in the case of an increase in speed due to the opening of the circuit downstream because of a maneuver, the collapse of a fuse plug, the breakdown of a seal or any other event which causes the downstream fluid flow.
The commonest installation is on service lines equipped with fuse plugs.
At the outbreak of a fire or as a result of a strong increase in the temperature in the protected installation, one or more fuse plugs collapse and let the fluid escape causing the REF 3000 to come into action.
