General information
The pressure reducer JRGURED UP is a compact
concealed valve for drinking water installations,
consisting of maintenance shut-off valve, coarse
filter and pressure reducer.
The built-in shut-off function is used
when maintaining the pressure reducer
and the downstream pipe installation.
Function
Water pressure in the installation system is to be
adjusted at an appropriate level.
The pressure-reducing valve JRGURED UP
decreases the inlet pressure to a lower,
constant outlet pressure.
The coarse filter integrated in the JRGURED UP
cartridge traps particulate matter greater than
1,000 µm. In case of significant pressure drop
when tapping water, clean or replace the coarse
filter (see Section 7).
