Manual Presetting Valves LENO™ MSV-B
Description
Application
LENO™ MSV-B is a new generation of manual
valves for balancing flow in heating, cooling and
domestic hot water systems.
LENO™ MSV-B is a combined presetting and shut
off valve with a range of unique features:
• Removable hand wheel for easy mounting.
• Numeric presetting scale, visible from more
angles.
• Easy locking of presetting.
• Built-in measuring nipples for 3mm needles.
• Open-close with Allen key in emergency.
• Open-closed colour indicator.
It is recommended to use LENO™ MSV-B in
constant flow systems in front of boilers, flat
stations or heat pumps in one-family houses
for balancing, shut off function for service and
repair, flow verification, one-pipe systems. The
valve may be mounted in flow or return.
DN 15 valves are available with internal or
external thread. Other dimensions with internal
thread.
Danfoss PFM 1000 measuring instruments
contain valve data for LENO™ MSV-B in memory.
Boiler, flat station or heat pump in 1-family
houses.
• For balancing.
• Shut-off function for service/repair.

Before fitting the valve the installer must ensure
that the pipe system is clean and:
1. the valve can be turned 360 degrees (if
threaded pipe is used).
2. the valve is fitted according to the flow
direction arrow.
Removal of the handle
1. Set the handle at 0/0.

Calibration of the handle
Before refitting, ensure that the handle setting
is 0/0.

Shut-Off
Setting and Locking
In order to shut-off the valve the handle must be
pressed down.
The shut-off function features a ball valve, which
only requires a 90 degree turn to shut the valve
completely.
An indicator window shows the actual setting:
• red = closed
• white = open
Measuring
The valve has a built-in presetting feature for
accurate flow ratings.
Setting the required flow is made in 5 steps:
1. In open position, release the lock using the
green lever or a 3 mm Allen key.
2. The handle pops up automatically.
The flow through the LENO™ MSV-B valve can
be measured using Danfoss PFM 1000 or other
brands of measuring instruments. The LENO™
MSV-B valve is supplied with two measuring
nipples for 3 mm needles. A twin bracket enables
the user to connect both needles simultanously.
Procedure for flow measuring:
1. Select flow measuring
2. Select valve brand
3. Select valve type and dimension
4. Enter presetting
5. Connect valve and instrument
6. Calibrate static pressure
7. Measure the flow
3. The calculated value can now be set.
4. The setting is locked when the handled is
pressed to click.
5. Seal - the setting can be protected by using a
strip as shown.

Kv-Signal
The red line indicates 25% of max. flow.
According to BS7350:1990 flow rates must be
within following values:
± 18 % at 25 % open position
± 10 % at fully open position
Kv-signal values are used for non-Danfoss
measuring instruments. Danfoss PFM1000 have
all data in memory, and the instruments are
using this formula:
Δp across the measuring nipples (k
across the valve (k
) is not the same due to
v-val
) and Δp

turbulence influence for pressure measuring.
LENO™ MSV-B is very accurate, due to the
separate functions for presetting and shut-off.

Δpr = 15 kPa
Δpa = 45 kPa
Δpm = 10 kPa
Δpi = Δpa – Δpv – Δpm
Δpi = 45 kPa – 15 kPa – 10KPa = 20 kPa
