Danfoss LENOTM MSV manual balancing valves are designed to be the most versatile and practical in their category. Where the installation of other valves can be a challenge due to limited space, the LENOTM MSV valves have a hand wheel that can temporarily be removed for easier installation in narrow spaces.

Features and benefits

Easy mounting
With a compact design and a hand wheel 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 set point locking

A simple tap on the top of the hand wheel is enough to lock the setting.
For more convenience, the LENO™ MSV-BD comes 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.

Easy shut-off function
When the LENO™ MSV 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. Closing the valve will not influence the flow setting because the setting mechanism and the shut-off mechanism are completely separate. The position (open or closed) is clearly shown by a red indicator.
