TECE flushing technology – U 1 urinal flush valve
U 1 TECE urinal flush valve
The TECE U 1 urinal flush valve is based on a further
development of tried and tested flush valve technology.
Well-conceived details and improved materials ensure a
long life and high reliability.
The TECE urinal flush valve is suitable for mechanical and
electronic actuation. The same housing is used in both
cases. The flush volume can be set from one to a maxi-
mum of about eight litres.

Housing for urinal flush valve and cartridges
Manual and electronic cartridges have the same flush
valve housing and the same high flush performance of >
0.3 l/s at 1 bar.
Using the following flow diagram, you can calculate the
flush volume for the urinal pressure flushing system
depending on mains pressure and flush time.

Example:
Mains pressure 3 bar: Flushing flow = 0.58 l/s
Flush time e.g. 3.5 s: Flush volume approx: 2 litres
The flush housing contains the inlet flow control, this is
adjusted using an Allen key (3 mm). A 90° anti-clockwise
turn closes the inlet flow control, a 90° clockwise turn
opens it.

Mechanical flush valve
The mechanical flush valve (to DIN EN 12541) is hydrau-
lically controlled and is sturdy and reliable. An automatic
jet cleaning function ensures long and maintenance-free
operation. The adjustable flush volume remains constant,
irrespective of the supply pressure.
Mechanical cartridge
Volume adjustment
The flush volume of the mechanical cartridge can be set
to 1, 2 or 4 litres using a retaining ring. When the retaining
ring is removed, the flusher can be set to 6 – 8 litres.
