New series of valves 732-D/ 738-D and 832-D/ 838-D for use with steam
The new steam pressure reducers are part of the well-known DRV 700 and DRV 800 valve series, are piston-operated, spring-loaded valves and have inlet pressure compensation. This means that strongly fluctuating inlet pressures have no significant influence on the set holding pressure. The holding pressure can be adjusted continuously between 2 - 10 bar as required. The valves are available with female thread to ISO 228 or flanges to DIN EN 1092. NPT or ANSI are also available as options.
Berluto pressure reducers of the DRV 732-D, 738-D or 832-D and 838-D series have been specially developed for use with steam up to 200°C. The carefully selected materials ensure optimum steam resistance in this range. With upstream pressures up to 16 bar and downstream pressures between 2 and 10 bar, our standard valves are suitable for a wide range of applications and enable flow rates from kvs-value 3.6 m³/h to 14.4 m³/h.
Berluto pressure reducers work with an integrated inlet pressure relief, which ensures a constant outlet pressure even if the inlet pressure fluctuates considerably. All nominal sizes are equipped with a removable cartridge for easy maintenance. We offer our steam pressure reducers as standard with female thread (ISO 228 or optional NPT - ASME B1.20.1) and DIN flanges (optional ANSI and JIS).
For optimum sealing even in demanding steam applications, only high-quality elastomers made of EPDM or FEPM are used. For high-temperature steam applications up to 200°C, we only use FEPM seals.
All metallic internal parts are made of stainless steel and therefore have a high resistance even against aggressive media.
All sizes have housing parts made of high-alloy cast steel 1.4408 with a very good general corrosion resistance. This makes them suitable not only for steam but also for critical media such as aggressive gases and liquids or, for example, demineralised water.
Our steam valves are available with female thread and as flanged versions.
