Description

Ordering

Strainer is installed to protect sensitive
equipment like meters, pumps, control valves
against danger caused by foreign particles and in
wide range of other applications.

Furthermore, strainer is available with a plug,
magnetic insert or ball valve. Combination with
ball valve allowing a quick and efficient cleaning.

Main data:

• DN 15-300

• PN 16/25
FVF strainer is designed for heating, district
heating and cooling systems.

• Temperature:

- Circulation water / water with glycol:

−10 … 150 °C (PN 16), −20 … 150 °C (PN 25)
Strainer removes and retains foreign particles like
welding beads, swarf, sand, etc. carried along by
heating / cooling medium.

• Connections:

- flange (strainer) DIN EN 1092-2

- thread (ball valve)

Installation positions

Standard screen Fine screen

The medium flow direction must correspond to
an arrow on the strainer body.

Strainers are to be installed in horizontal position
with mesh bonet directed downwards. Vertical
position is also allowed (be aware - when
medium flows upwards strainer retains all
foreign particles but is not able to collect them).

Sufficient space to pull out the mesh for
replacement and cleaning must be ensured.
