Method of Operation

Descrizione
FY71P-65B DN = 65 - Kvs 107 The inlet pressure has no influence in either opening or closing of
Spring loaded pressure reducing valves operate by means of a
force equalizing system. The force of a diaphragm operates the valve. Because of this, inlet pressure fluctuation does not
FY71P-80B DN = 80 - Kvs 151 influence the outlet pressure, thus providing inlet pressure
against the force of an adjustment spring. If the outlet pressure

and therefore diaphragm force fall
FY71P-150B DN = 150 - Kvs 378
then greater force of the spring causes the valve to open. The
outlet pressure then increases until the forces between the
diaphragm and the spring are equal again.

Installation Guidelines Typical Applications
• Install in horizontal pipework with spring bonnet directed Pressure reducing valves of this type are suitable for multi
upwards dwelling buildings, industrial and commercial applications within
• Install shut-off valves the range of their specifications.
• The installation location should be protected against frost The pressure reducing valve should be installed, if one or more
and be easily accessible: of the following conditions apply:
- Pressure gauge can be read off easily
- Simplified maintenance and cleaning • The static pressure exceeds the maximum permissible value
• Install downstream of the filter or strainer. This position • for the system.
Several pressure zones are required when a pressurisation
ensures optimum protection for the pressure reducing valve system is used (pressure reducers on each storey of a
against dirt.
• Provide a straight section of pipework of at least five times the building).
nominal valve size after the pressure reducing valve (in • Pressure fluctuations in the downstream system must be
accordance with DIN EN806 part 2) avoided.
• To achieve constant inlet and outlet pressures on pumped
pressure boosting systems.
• To reduce the water consumption.
