Building technology

Our wide range of products optimally supports the diverse applications in the field of building services engineering. Be it in the area of compressed air treatment systems or in the workshop environment, in sanitary and waste water systems or in the area of fire extinguishing or pressure boosting systems.

The wide range of sizes, pressure and temperature ranges allows you to choose the valve that best suits your application.

Features

  • Seals

    Depending on the design, there is a choice of NBR, EPDM or FKM seals, which allow media temperatures of up to 190°C. Our EPDM seals have the required ELL and W270 approvals, which allow their use with drinking water.

  • Wetted parts

    Depending on the design and size, metallic or plastic internal parts are used. A large number of our pressure reducers have easily replaceable cartridges, which reduce the necessary maintenance to a minimum.

  • Body

    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 the drinking water sector and is known for its high corrosion resistance. High-alloy cast steel has a very good general corrosion resistance.

  • Connections

    Our valves are available in all common connection types from female thread to male thread and flanged versions.
