Often the temperature range of standard pressure reducers is not sufficient for your application. For such applications, various variants of the -HT series are available. This high temperature series is equipped with FKM seals (DRV 6-series EPDM). Thus, a maximum temperature resistance of 190°C (DRV 6-series 130°C) is achieved with FKM seals in combination with metallic internal parts.
Bitte beachten Sie, dass diese Druckminderer nicht für den Einsatz mit Dampf geeignet sind, für Dampfanwendungen stehen Ihnen unsere besonders für dieses Anwendungsfeld entwickelten Druckminderer der Baureihen 732-D/ 738-D und 832-D/ 838-D zur Verfügung (mehr erfahren...).
Only FKM seals are used for use at high temperatures. These offer resistance up to 190°C (6-series EPDM up to 130°C).
For high-temperature applications, only metallic internal parts are used in our pressure reducers of the -HT series.
Depending on the series, the housing parts are made of red bronze (CuSn5Zn5Pb2-C-GS / CC491K, "RG5") or high-alloy cast steel 1.4408. Red bronze has been used for decades in drinking water and seawater applications and is known for its high resistance to seawater corrosion. High-alloy cast steel 1.4408 has a very good general corrosion resistance.
Our pressure reducers of the -HT series are available in all common connection forms from female thread to male thread and flanged versions.
