Pressure reducing valves made of gunmetal, with flange connections

Often flange pressure reducing valves with smaller connection sizes are required. For this reason, this type is now not only available in sizes DN65 and DN100, but also in sizes DN20 to DN50, as well as in a high- and low-pressure version. The body is made completely of corrosion-proof and seawater-resistant gunmetal. All wetted parts are made either of gunmetal or corrosion-resistant stainless steel.
All technical features of the stainless steel version have also been consistently incorporated into this version.
