About SferaTec Gebäudetechnik
SferaTec Gebäudetechnik GmbH has been active since 1989 as a manufacturer and supplier of valves and hydraulic components for building and industrial engineering. The company supplies manufacturers, the plumbing and heating trade (SHK) and plant engineering with components made of brass, gunmetal and stainless steel – both from its own range and manufactured to customer drawings. The product portfolio includes ball valves (manual and motorized), gate valves, valves, balancing valves, threaded fittings and unions, pump groups and fresh water stations, diaphragm expansion vessels as well as plastic tanks made of polyethylene. A key focus is on lead-free materials (CW511L-DW, CW724R-DW) and a stainless steel product line introduced in 2025 for drinking water and process applications. SferaTec is the sales partner of Cimberio and Elbi in Germany and supports customers with CAD-supported product development, technical consulting, warehousing, just-in-time deliveries and worldwide shipping including customs clearance. The company is headquartered in Kürten near Bergisch Gladbach.

Materials and Processes
Lead-free brass
For drinking water applications; a large range is already available lead-free, with further products manufactured lead-free to customer specification.
Lead-free brass
Lead-free brass alloy for future-proof drinking water and system engineering.
DZR brass (Pb max. 0.1 %)
Dezincification-resistant, lead-free brass, e.g. for the male-thread strainer series PN 25.
Brass
Base material for valves, fittings and valve bodies (e.g. SecurFix base body).
Gunmetal
For pressure-resistant valves and unions in heating and sanitary applications.
Stainless steel
Stainless steel product line for corrosion-resistant, hygienic applications with drinking water, food and process media.
Polyethylene
Material of the Elbi Plasto storage tanks for storing water and suitable media.
