FVR
FV strainer is used in heating and hotwaterservice systems to protect the fittings. The
strainer filter traps foreign matters in the pipe
water like welding beads, swarf, sand, etc.FV
must be fitted in the system flow to protect the
fittings from external foreign matters. FV must
also be fitted ahead of sensitive components like
meters, pumps,control valves to protect against
internal foreign matters.

Installation positions 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.
