General
The pressure-reducing valve JRGURED is a
compact fitting for water systems*, consisting
of a coarse filter and a pressure-reducing valve.
* Other applications on request.
The coarse filter incorporated as a standard
feature retains suspended particles, which
are larger than 1'000 micron.
Recommendation
In order to protect the pressure-reducing valve
JRGURED as well as the complete domestic
water supply system from suspended particles
and contaminations from the public water supply
mains, we recommend the installation of a JRG
fine filter (1830-1846) with a filtering capacity
of 100 micron ahead of the pressure-reducing
valve.
