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
