1 JRG JRGURED Pressure reducing valves
2 JRGURED The JRGURED pressure reducing valves is a compact fitting for water systems consisting of a strainer and a pressure reducing valve. The strainer incorporated ahead of the pressure reducing valve as a standard feature keeps out suspended particles which are larger than micron. In case of need or if there should be a significant pressure drop during the consumption of water, the strainer can be cleaned easily. The shapely JRGURED pressure reducing valve not only impresses with its performance values, but also with the price-performance ratio. The fitting, which is tested and approved by the SVGW is patented and thanks to its sophisticated modular design fulfils all demands which are made of an inline-with-the-times armature. The JRGURED pressure reducing valve is designed for the nominal pressure PN 2500 kpa (25 bar) and is available in four versions, sies ½ to 2½. The works pressure settings can easily be adapted to the hydraulic conditions on site by a plumbing specialist. Depending on the version, the fitting can accept water temperatures up to 70 C. The JRGURED pressure reducing valve has the same installation measurements as its predecessor and therefore a problem-free exchange is possible. 1 Gunmetal body 2 Slide with seat 3 Permaphragm 4 Valve seal 5 Pressure springs 6 Valve cover 7 Tensioning screw 8 Strainer 9 Transparent or gunmetal strainer cup 10 O-ring seal 11 Pressure adjustment 12 Allen key 2

For systems with different pressure levels, several pressure reducing valves with different secondary pressures have to be utilied. p Appliance-, machine-connections with a separate pressure reducing valve Appliances or machines can if so required be connected through their own pressure reducing valve. In doing so, the prescriptions of the manufacturer of the appliance or machine as well as the installation prescriptions of the local water supply have to be complied with. 3

The JRGURED pressure reducing valve has to be built into the line free of any tension at an easily accessible location. For the strainer maintenance, a distance of 60 mm is necessary. JRGURED pressure reducing valves with plastic filter cups have to be installed in such a manner, that they are protected from intensive UV radiation. 2 versions for different temperatures Easy cleaning of strainer Minimum installation height Same installation length as JRGURED 1130 Installation prescriptions For the installation of JRGURED pressure reducing valves, please apply the country-specific guidelines. 4 tested and approved.
