Berluto DRV 303 / 373 pressure reducing valve, drinking water
Compact diaphragm pressure reducing valve in red bronze with plastic inner parts, female thread G 1/2" to G 1 1/4", inlet up to 16 bar, outlet 1.5 to 6 bar (303) or 0.5 to 4 bar (373), for water and drinking water up to 75 °C.
The DRV 303 / 373 is Berluto’s light-duty threaded reducer for water. The red bronze body carries a Hostaform C plastic bonnet and plastic wetted inner parts, which keeps the valve compact, light and suited to drinking water when fitted with EPDM seals. Inlet pressure is limited to 16 bar and the medium temperature to 75 °C.
The 303 sets outlet pressures between 1.5 and 6 bar, the 373 between 0.5 and 4 bar. Both are diaphragm controlled with inlet pressure compensation, have an integrated strainer and a replaceable cartridge, and offer gauge ports on both sides. Four sizes cover G 1/2” to G 1 1/4”.
The male-thread counterpart with the same internals is the DRV 403 / 473, which carries the DVGW type approval.
Selection data we need
Medium and temperature, inlet pressure, required outlet pressure, flow rate or Kvs, connection size, and whether drinking water conformity is required.
Applications
