CLAYTON Pipe burst safety valve


The CLAYTON Pipe burst safety valve is equipped with an orifice plate on the inlet side. When the flow reaches the specified pipe break volume and thus also the specified differential pressure, the valve closes.
After the pipe burst has been repaired, the pipe burst protection valve must be put back into operation.

Minimum inlet pressure 0.2 bar, minimum differential pressure 0.5 bar.
Differential pressure orifice 0.3 bar.
