Profipress

Press connector system with press connectors made of copper, gunmetal or silicon bronze*, tested in acc. with DVGW worksheet W 534 with DVGW test seal and pipes made of copper in acc. with DIN EN 1057 and DVGW worksheet GW 392. Suitable for potable water installations in acc. with DIN 1988.For dimensionally stable concealed and pre-​wall installations of manifold and riser pipes in Viega component assembly.

Press connectors
All sizes with SC‑Contur – accidently unpressed connections become visible during filling the system. The SC‑Contur is certified and fulfils the requirements of the DVGW worksheet W 534, point 12.14, Connectors with forced leakage.
During leakage tests with water Viega guarantees the identification of unpressed connections in the pressure range 0.1 MPa–0.65 MPa, in the case of dry leakage tests with compressed air or noble gases from 22 hPa–0.3 MPa.

Marking
Green dot on the press connection

Sealing elements
EPDM, black (ethylene-​propylene-​diene-​monomer rubber); up to 110 °C; not resistant against hydrocarbon solvent, chlorinated hydrocarbon solvents, turpentine, petrol

Press connector materials
Copper, gunmetal: CC 499K
Silicon bronze*: CC 246E / CuSi4Zn9MnP
(both in acc. with UBA list dated 15th March 2017)

Special applications
with EPDM sealing element, factory-​fitted

• Stationary sprinkler-​extinguishing systems – with VdS certificate G 4980009 for the sizes DN20–DN50 in combination with copper pipes in acc. with DIN EN 1057 R290 (hard)
• Solar installations with flat collectors

with FKM sealing element (accessories)

• Solar installations with flat/vacuum collectors
• District heat suppliers and low-​pressure steam systems

The use of the system for other than those described areas of application and media must be approved by the Viega Service Center.

Operating conditions
Potable water installations

• Operating temperature max. 85 °C
• Operating pressure max. 1.6 MPa

Heating installations

• Operating temperature max. 110 °C
• Operating pressure max. 1.6 MPa

Note
Observe flow direction!
Components made of copper may not be installed upstream from galvanised ferrous materials!

Note – Limitations of use potable water
With regard to the possible exceeding of the limit value for copper ions according to the Potable Water Ordinance (TrinkwV), pipes and connectors made of copper may only be used when the pH value is ≥ 7.4 or the total volume of organic carbon does not exceed TOC = 1.5 mg/l at values between pH = 7.0–7.4!

Note for copper pipes with internal tin plating acc. to DIN 50930‑6:
Copper pipes with internal tin plating in combination with non-​tin-​plated copper press connectors can be used for all potable water according to the Potable Water Ordinance (TrinkwV). There is only a negligible risk of the limit value being exceeded due to the migration of copper ions into the tap water as a result of the comparatively low surface areas of the non-​tin-​plated connectors vis-à-vis those of the pipes!

Further information on the use and impact of copper materials can be found in DIN EN 12502‑2. Should you have specific questions, please contact Viega's technical consultation team: service-​technik@viega.de

Note – Limitations of use heating systems
Please observe VDI 2035 and DIN EN 12828!

Use of press tools
The functional safety of the Viega press connector systems primarily depends on the perfect condition of the press tools and press machines used. For this reason, for the production of press connections we recommend the use of Viega press tools and their regular inspection by authorised service points.

Technical data
Press connectors and components are constantly being optimised. If required, the current Z and installation dimensions can be obtained from the download area of the Viega homepage: www.viega.com/downloads

Accessories for use with Easytop fittings, see product area system fittings.

*) Change of material due to the current switch of production from gunmetal to the Viega worldwide uniform silicon bronze alloy
