Verafix-MES-II
PRODUCT DATA
Application
The Verafix-MES-II is a radiator lockshield valve with
measuring support for the supply or return of radiators or heat
exchangers. It is used for measuring, shutoff and draining/filling
of individual radiators in two-pipe heating systems. In combination with a pre-settable TRV body the Honeywell measuring
method can be applied: measuring and pre-setting at the same
time.
The Verafix-MES-II is suitable for hot water heating systems
and cold water cooling systems.
Features
• Measuring and pre-setting at the same time
• Measuring, shutoff and draining/filling with one valve
• Optional flow direction. Performance values apply for
both directions
• Piston externally O-ring sealed
• Body dimensions to DIN3842
• Robust corrosion-resistant red bronze housing
• Connection to all types of pipe DN10...DN20
• Easy identification: cover cap with hexagon and raised
circular centre; also see illustrations identification

V2410 - VERAFIX-MES-II
Function
The Verafix-MES-II connects the return of a radiator or heat
exchanger to the water loop and has the functions measuring,
shutoff and draining/filling.
Measuring:
To measure the flow the VA3301A measuring adapter is
connected to the Verafix-MES-II and a measuring device, for
example BasicMES is connected to the measuring adapter.
Pre-setting of the required flow rate is done using the Honeywell measuring method: the water quantity is measured and is
then adjusted as required on the pre-settable V, FV or SC type
TRV. Closing or opening of the TRV is immediately indicated
on the measuring device as a lower or higher flow rate.
The Verafix-MES-II has two fixed kv-values: measuring
range II (standard) and measuring range I for low flow rates.
The valve is supplied set to measuring range II.
For correct measurements the right measuring range or kvvalue has to be fed into the measuring device.
Also see chapter ‘Flow Diagram’.
NOTE: Measuring and pre-setting at the same time can only
be done when a pre-settable TRV body is installed,
e.g. Honeywell VS, FS, FV or SC type.
Shutoff:
The return of the radiator can be shutof f by clo si n g the valve
insert.
Draining:
Draining or filling of the radiator is carried out with the draining
adapter (see ‘Accessories’). Draining of individual radiators
using the Verafix-MES-II has no influence on the heating loop
or other radiators in the loop.
Detailed illustrations of above functions see chapter Shutoff/
Draining and Change to Measuring Range I
Please Note:
• To avoid stone deposit and corrosion the composition of the
medium should conform with VDI-Guideline 2035
• Additives have to be suitable for EPDM sealings
• System has to be flushed thoroughly before initial operation
with all valves fully open
• Any complaints or costs resulting from non-compliance with
above rules will not be accepted by Honeywell
• Please contact us if you should have any special requirements or needs
