Manual balancing valves

  • Flexible solutions with LENO™ balancing valves

    Life is challenging for all of us. Projects to complete, deadlines to meet, and customers to satisfy. That is why Danfoss has asked its engineers to look at a manual balancing valve and design the best products imaginable. The result is the LENO™ product range. It offers many possibilities to make your daily job easier and more effective.


  • What's in it for you?


  • Easy mounting

    More building space, less money! This is possible with LENO™

    With a compact design and a handle, easy to remove, you need just a tiny room for installation. Conventional balancing valves need to be mounted in straight pipe to ensure accurate measurement. The LENO™ can be placed anywhere, for example just after an elbow, without influencing its accuracy.

    Easy and accurate measuring

    LENO™ is always accessible with its measuring nipples and measuring station.

    The digital scale is easy to read from all angles. The precision of the valve is independent of the setting and much more accurate than competing solutions. For saving your time, Danfoss introduces you to a hightech measuring device. The PFM5000 allows you to carry out measurement with your mobile phone (Android App) with either bluetooth or wireless.

    Easy set point locking

    A simple tap on the top of the handle is enough to lock the LENO's setting.

    For more convenience we ship the LENO™ MSV-BD with a green disposable key for unlocking. Simply press the green latch and the valve is unlocked. To make LENO™ tamper-proof a plastic tie-wrap (accessory) can be inserted. It makes it easily visible when the valve has been tampered with.

    Easy shut-off function

    When the LENO™ MSV-BD is locked, the valve becomes a ball valve. This feature has several advantages: The valve has zero leakage, opening and closing the valve is much easier. It takes only a quarter turn and closing the valve will not influence the setting because the setting mechanism and the shut-off mechanism are completely separate. The position of the LENO™ (open or closed) is clearly shown by a red indicator.
