Sluice-Gate Fitting Device (DWG 1) is an innovating conception device that allows to make easier and to lower time and resources necessary for plugging intervention on pressure fluids supply pipes. The Sluice-Gate Fitting Device meets the double function of fitting for equipment assembly and anti-leakage valve of the pressure fluid during the operation of plugging interventions.
The Sluice-Gate Fitting Device allows the operation of plugging intervention on pressure pipes without using a valve for equipment assembly (as they are assembled directly on the fitting with a proper fixing flange) and with an internal locking system safer an more efficient of traditional ones.
