Berluto DRV 350 low-pressure reducing valve
Low-pressure diaphragm reducing valve in red bronze with an enlarged diaphragm for fine control, female thread G 1/2" to G 2", inlet up to 16 bar, outlet 0.2 to 2 bar, for water, neutral liquids, air and neutral gases.
The DRV 350 is Berluto’s low-pressure reducer in red bronze with female thread. An enlarged control diaphragm gives it the sensitivity to hold outlet pressures between 0.2 and 2 bar accurately, from an inlet of up to 16 bar. The diaphragm sits under a PA6 bonnet up to DN 32 and a cast iron bonnet from DN 40.
Otherwise the valve follows the family pattern: pressure compensation, continuous adjustment, an integrated strainer, a replaceable cartridge and G 1/4” gauge ports on both sides. Sizes run from G 1/2” to G 2” with Kvs values from 2.9 to 13 m³/h.
NBR, EPDM (also with FDA conformity) or FKM seals cover −30 °C to +190 °C; the high-temperature version uses FKM with brass internals.
Selection data we need
Medium and temperature, inlet pressure, required outlet pressure, flow rate or Kvs, connection size and thread 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
- Feed lines to low-pressure equipment and open vessels
