LEAKS FROM PREMITRECCIA
Fluid leaks through packing or pre-formed graphite rings are a fairly frequent problem, especially where high pressures are present (eg water-steam circuits in thermoelectric power plants).
In these cases, we intervene by drilling holes directly on the castle in correspondence of the chamber chamber and injecting the sealing compound until the seal pack is reconstructed.
The intervention partially affects the maneuverability of the valve.
