Design

The lockshield valve consists of:

•Valve housing PN10, DN10, 15 or 20 with

•internal thread connection to DIN2999 (ISO7) or external thread connection to DIN/ISO228 on inlet

•external thread connection to DIN/ISO228 with union-nut and radiator tailpiece (not V2406) on outlet

•Body dimensions to DIN3842

•Valve insert

•Protection cap

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 shutoff by closing 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
