Coordinate the use of the model for areas of use and media other than those described with the Viega Service Center.
The functionality of the valve is only ensured by professional design and assembly of the complete system.
Use is possible in the following areas among others:
Hot water circulation pipelines
Internally and parallel laid circulation pipes
The general rules of engineering and the applicable regulations must be observed for planning, execution, operation and maintenance potable water installations, see Regulations from section: Fields of application .
The model is also suitable for the following media, amongst others:
Drinking water without limitations acc. to the applicable directives, see Regulations from section: Media
maximum chloride concentration 250 mg/l pursuant to applicable regulations, see Regulations from section: Media
According to the applicable regulations, Easytop system fittings can be used for all types of potable water and are DVGW certified, see Regulations from section: Product description . Their plastic components comply with the KTW recommendation and the requirements pursuant to the applicable regulations.
The model is equipped as follows:
valve casing made of gunmetal/silicon bronze
valve top made of gunmetal/silicon bronze
dual-sided G external thread
drain plugs for drainage valve G ¼
setting scale
handwheel with exchangeable coloured plastic cap as media labelling
key surface on the casing
The static circulation regulation valve can be used to equalise and shut-off pipe sections. The set flowthrough volume can be fixed mechanically. The set value is not altered by opening and closing the valve.
The model is available in the following dimensions:
DN |
---|
G |
15 | 20 | 25 |
¾ | 1 | 1¼ |
Only flat sealing connection screw fittings may be used for the threaded connection.
Sealing of the G-threads takes place by pressing the sealing surfaces together. For this reason, no additional sealants (hemp, sealing paste / thread etc.) may be used.
The model is marked as follows:
flow direction indicator
dimension
DVGW writing
setting scale
The model is equipped with G-external threads according to the applicable regulations and compatible with the Profipress, Sanpress, and Sanpress Inox system, see Regulations from section: Compatible components .
The static Easytop circulation regulation valve is used in circulation pipes and allows hydraulic line calibration. The calibration takes place via a reproducible presetting.
Observe the following operating conditions for the installation of the model:

90 °C |
1.0 MPa (10 bar) |
0 - 6.9 |
The required set values can be obtained from the diagrams below. The intermediate values can be set steplessly.
Overground pipelines and fittings in rooms do not normally require external corrosion protection.
There are exceptions in the following cases:
Contact with aggressive building materials such as nitrite or materials containing ammonium
in aggressive surroundings
If external corrosion protection is required, observe the pertinent guidelines, see Regulations from section: Corrosion .
Easytop fittings made of gunmetal/silicon bronze are suitable for all types of potable water.
The chloride concentration in the medium must not exceed a maximum value of 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the content in sea and table salt (sodium chloride).
The following optional accessories are available:
Drainage valve
Thermometer
Insulating shell
EPS insulating shells are available for the static circulation regulation valve. The two-piece insulating shells are self-supporting and are mounted without tools and holding grips. They close seamlessly on the front surface of the pipeline insulation.
Do not remove the model from the packaging until immediately before use.
System components may, in some cases, become damaged through transportation and storage.
Check all parts.
Replace damaged components.
Do not repair damaged components.
Contaminated components may not be installed.
Observe the following when mounting:
use suitable tools
flow direction indicator
When tightening the connection screw fitting, counter by holding the key surface of the valve.
A piece of straight pipe of at least 3xd should be installed upstream from the fitting.
Choose the place of installation so that the fitting is easily accessible, simple to operate and the insulating shell can be well mounted.
For information, refer to the instructions for use of the Profipress, Sanpress and Sanpress Inox systems.
For information, refer to the instructions for use of the Profipress, Sanpress and Sanpress Inox systems.
An Allen key (size 2) is required to pre-set the target values.
Installation is possible in the riser pipe.
If there are multiple riser pipes on the storey during the installation of the thermostatic circulation regulation valve, then every riser pipe must have a circulation regulation valve mounted, see Static CRV in the riser pipe .
According to the applicable directives, circulation regulation valves must be installed between the outlet of the hot water tank and the circulation inlet, see Regulations from section: Installation position and settings .
Set the calculated flow values (see Target values ) before commissioning.
Setting is shown using model 2282 as an example.
Before commissioning:
Set the valve to the calculated flow value.
The set flow quantity can be fixed mechanically. We recommend the following steps to prevent the set value being adjusted by the opening and closing of the valve:
Remove the cover.
Mark the position of the handwheel on the spindles.
Remove the handwheel.
Loosen the screw with the Allen key (SS 2).
Screw the adjusting screw (SS 11) into the valve as far as it will go; at the same time, hold the spindle (SS 6) tight.
Tighten the screw again with the Allen key (SS 2).
Position the handwheel as marked and mount the lid.
The circulation regulation valve is now ready for use.
The installer must perform a leakage test before commissioning.
Carry out this test on a system that is finished but not yet covered.
Comply with the general rules of engineering and the applicable directives, see Regulations from section: Leakage test .
Document the result.
Inform your customer or the operator of the drinking water installation that the system has to be maintained on a regular basis.
Observe the applicable regulations for the operation and maintenance of drinking water installations, see Regulations from section: Maintenance .
Separate the product and packaging materials (e. g. paper, metal, plastic or non-ferrous metals) and dispose of in accordance with valid national legal requirements.
