Euro. Co. Met. proposes two types of valves to be used for the injection of cement grouts, i.e. semi-liquid mixtures of water and cement used in the restoration field.
Manchette valves: when a series of coupled holes covered by a rubber sheath protected by steel rings welded to the pipe are applied to the steel pipe.
Retractable valves: they have a specially designed rubber compound inside them that closes immediately after injection.
These are drilled, using a drill, in diameters of 12 and 16 centimetres. We can also drill to specific client specifications.
