Pressure reducing valves made of stainless steel, with threaded connections

New applications can now be covered by Goetze's well-proven, robust pressure reducing valve with threaded connections now that they have extended their gunmetal series 681 to include a stainless steel version. The new 481 offers all the advantages of the 681 – while at the same time withstanding very critical and aggressive media and environments. Additional outlet pressure ranges of 0,5 to 2 bar and 5 to 15 bar make this valve suitable for an even wider range of applications.
