Berluto DRV 572 / 578 wide-range pressure reducing valve, flanged
Wide-range diaphragm pressure reducing valve in red bronze with PN 25 flanges DN 15 to DN 80, inlet up to 25 bar, outlet 0.5 to 4 bar (572) or 0.5 to 9 bar (578), for water, neutral liquids, air and neutral gases.
The DRV 572 / 578 is the wide-range reducer of Berluto’s flanged 5xx series in red bronze. A larger diaphragm and softer springs let it hold outlet pressures from 0.5 bar while accepting up to 25 bar inlet; the 572 covers 0.5 to 4 bar, the 578 0.5 to 9 bar, in DN 15 to DN 80 with PN 25 flanges.
Inlet 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 (also with FDA conformity) or FKM seals cover −30 °C to +190 °C.
Selection data we need
Medium and temperature, minimum and maximum inlet pressure, required outlet pressure, flow rate or Kvs, nominal size and flange standard, seal material.
Applications
- Low outlet pressures from a high supply pressure
- Water and neutral, non-sticky liquids
- Compressed air and neutral gases at higher flow rates
- Flanged building services and industrial utility lines
