Features
Pressure reducers are membrane pressure reducers with inspectionable and easily interchangeable internal cartridge, complete with removable filter. The cartridge is a compensated seat: upstream pressure variations do not affect the adjustment of the downstream pressure.
The main purpose of the pressure reducing valve is to reduce the fluid pressure to optimal values, constantly below the maximum allowed in order to avoid damaging the utilities placed downstream of the reducer.
Pressure reducers are intended to be used in the plumbing, heating and sanitary systems with upstream pressure not higher than 16 bar.
The pressure reducer is pre-set in the factory with an output pressure adjustment: P = 3 bar (300 kPa).
The correct number of pressure reducers necessary for the pressure reduction is important to avoid cavitation. These phenomena, in fact, create an excessive noise in the reducer, with consequent problems for the utilities and possible damage of the reducer itself. For this reason, please refer to the dedicated section inside the technical data sheet for the optimal choice of the number of reducers in relation to the pressure variation to be obtained.
