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.
To save costs for shut-off valves the LENOTM MSV-BD, MSV-B and MSV-O valves combine both a balancing and shut-off function. For that purpose, the principle design is based on a ball valve, making sure the shut-off offers 100% watertight
closure of the system. Using the shut-off ball valve will not influence the flow settings. Furthermore, the numeric pre-setting indications can be viewed from different angles making commissioning easier.
All three types of LENOTM MSV valves offer built-in measuring nipples for 3 mm needles. In case of the MSV-BD these can, together with the draining, even be rotated over 360° to any preferred position. The MSV-O has a fixed venturi orifice. The MSV-S is a supplementary shut-off valve with built-in draining.
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.
