Pressure reducers are used:
In plumbing systems:
- to maintain constant water pressure in the distribution network downstream of the reducer
- to prevent excessive water withdrawals by controlling the pressure at the taps
- To keep the water pressure constantly below the maximum allowable value
In compressed air systems:
- to keep the pressure in the network constant, regardless of fluctuations in the pressure supplied by the compressors
Downstream of storage tanks or cylinders:
- To reduce and stabilize the pressure in the network that is normally lower
In addition to water, pressure reducers are also used for air and gas (neutral). DRV, DRVM, DRVN, DRVMN Series pressure reducers are of the compensated seat type. This means that the inlet pressure, acting on the two openings having the same cross section, is compensated and therefore exerts no force on the poppet pin system as the degree of opening of the reducer changes.
Instead, the outlet pressure acts on the diaphragm and thus on the pin-obturator system, which is thus subject to two opposing forces: that exerted by the outlet pressure, which tends to close the shutter, and that exerted by the spring, which tends to open it. The result is a behavior of the compensated seat reducer having the outlet pressure virtually insensitive to changes in upstream pressures.
