LENO™ MSV-BD and MSV-S: The Perfect Match!

The new LENO™ Family has been developed to have the best range of manual balancing valves in the Danfoss product portfolio. LENO™ MSV-BD has the best features of all manual balancing valves on the market, and LENO™ MSV-S is a high quality ball valve, which makes it a strong partner valve for LENO™ MSV-BD. Almost all terminal units and systems has two connections, supply (MSV-BD) and return (MSV-S). When Danfoss delivers LENO™ MSV-set for flow and return, Danfoss has simplified logistics by bunding LENO™ MSV-BD and LENO MSV-S together.

LENO™ MSV-S can be used together with LENO™ MSV-BD or another manual balancing valve from the LENO™ series. The two valves can be mounted together insuring the right flow and you have the possibility to shut off a partt of the system or a terminal unit and drain it. The valves have a broad working area. LENO™ valves are constructed to deliver high flows, and they are very accurate at low flows. The precision of the valves is independent of the setting, and much more precise than competing solutions.


LENO™, as easy as falling of a log...

1. Easy mounting: The LENO™ is very compact and the handle is easy to remove so you need very little room for the installation.
2. Easy and accurate measuring: LENO™ has measuring nipples on a measuring station so they are always accessible. The digital scale is also readable from all angles. - Danfoss also introduces a high-tech measuring device. The PFM4000 allows you to carry out the measurements wit either Bluetooth or wireless technology which saves a lot of time.-
3. Easy set point locking: A simple tap on the top of the handle is enough to lock the LENO™’s setting.
4. 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 because it takes only a quarter turn and closing the valve will not influence the setting in any way because the setting mechanism and the shut-off mechanism are completely separate. MSV-S is already a zero-leakage ball valve.
5. Easy and practical draining: LENO™ has a built-in drain tap. To drain you can use a 6 mm allen key for the MSV-S and turn one of the measuring nipples with a 13 mm spanner for the MSV-BD. When the LENO™ is closed, you can even choose from which side of the value you want to drain by selecting the appropriate measuring nipple, saving you the expense of mounting additional drain taps.
6. High quality ball valve: LENO™ MSV-S has a handle where the distance from the handle to the pipe, insures the installer space to mount insulation.

Because almost every terminal unit and system has at least two pipes (one supply pipe and one return pipe), Danfoss has bundled up the perfect match to save your time and simplify logistics; LENO™ valves together in order to propose LENO™ sets. LENO™ sets contain two valves placed in one box. These are LENO™ MSV-BD and LENO™ MSV-S, both of the same diameter
