3. Foot valves and non-return valves
BV, MV 3/4" to 3"
BV and MV valves are one-way valves with the valve
casing made of cast iron or bronze. The valves have
internal pipe thread and can be supplied with or
without spring-loaded valve cone.
Applications
BV and MV valves are used in minor water supply and
pumping systems to avoid backflow when the pump is
stopped. The valves are also fitted in systems where
the pumps are connected in parallel and as foot valves
to secure the suction conditions of the pumps.
Valves without a spring are only intended for vertical
installation. Valves with a spring can be fitted in any
position in the pipe system.
