    Pressure relief valves HEROSE

    Thanks to the safety valve, you can easily drain the medium - air, water, gases, etc. in case of excessive pressure. All insurance valves offered by us meet the relevant TÜV standard for the respective medium. We deliver the products set to your required pressure, sealed with TÜV certification. For more information, click continue.

    Overpressure can not only destroy your equipment connected to the compressor, but also endanger you directly. Excess pressure can be easily "blown off" from the compressor system by means of a safety valve, which is simply installed on a thread. It is not only for compressors. Safety valves are used on pressure vessels, boilers, heating systems, heaters and all systems that need to be protected from exceeding the required allowable pressure.

    What can I forgive with a safety valve?

    • refrigerant
    • steam
    • gas
    • bulk materials
    • water
    • air

    We always tell you directly in the product description which medium the safety valve is used for. Please take care, because the valves are made of materials that are not harmful in connection with certain types of media - e.g. no corrosion. The following categories will also make your choice easier:

    Relief valves divided by type of medium

    As safety valves are devices that involve pressure and its associated hazards, each valve must be TÜV-approved and certified. With us, you always buy a valve with complete certification, set and sealed - i.e. with a complete package of relevant documentation... in short, "full service". You only need to screw in the safety valve and then enjoy the correct pressure in the entire pressure system, which is gentle on all components.
