Berluto DRV 550 low-pressure reducing valve, flanged
Low-pressure diaphragm reducing valve in red bronze with PN 25 flanges DN 15 to DN 80, inlet up to 16 bar, outlet 0.2 to 2 bar, for water, neutral liquids, air and neutral gases.
The DRV 550 is the low-pressure reducer of Berluto’s flanged 5xx series in red bronze. Its enlarged diaphragm holds outlet pressures between 0.2 and 2 bar accurately from an inlet of up to 16 bar, in DN 15 to DN 80 with PN 25 flanges.
Pressure compensation, continuous adjustment, an integrated strainer, a replaceable cartridge and G 1/4” gauge ports on both sides are standard. Kvs values run from 2.9 to 18 m³/h. NBR, EPDM or FKM seals cover −30 °C to +190 °C, with a high-temperature version using FKM and brass internals.
Selection data we need
Medium and temperature, inlet pressure, required outlet pressure, flow rate or Kvs, nominal size and flange standard, seal material.
Applications
- Outlet pressures below 2 bar with precise adjustment
- Water and neutral, non-sticky liquids
- Compressed air and neutral gases at higher flow rates
- Flanged feed lines to low-pressure equipment
