Berluto DRV 750 low-pressure reducing valve, stainless steel
Low-pressure diaphragm reducing valve in stainless steel 1.4408 with an enlarged diaphragm, female thread G 1/2" to G 2" (or male thread R with the -R version), inlet up to 25 bar, outlet 0.2 to 2 bar, for aggressive liquids, air and neutral gases.
The DRV 750 is the low-pressure reducer of Berluto’s stainless steel threaded line. 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 25 bar. Body and bonnet are stainless steel 1.4408 with 1.4404 inner parts, for aggressive liquids, air and neutral gases.
Pressure compensation, continuous adjustment, an integrated strainer, a replaceable cartridge and G 1/4” gauge ports on both sides are standard, as on the rest of the 7xx series. 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 -R version has male thread ISO 7 (R 1/2” to R 2”); its datasheet is attached below. For outlet pressures in the mbar range see the DRV 740.
Selection data we need
Medium and temperature, inlet pressure, required outlet pressure, flow rate or Kvs, connection type (female G or male R) and size, seal material.
Applications
- Outlet pressures below 2 bar with precise adjustment
- Aggressive water and other aggressive liquids
- Compressed air and neutral gases at higher flow rates
- Chemical, pharmaceutical and food plants (EPDM with FDA conformity)
