Spring loaded pressure reducing valves operate by means of a The inlet pressure has no influence in either opening or closing of

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.
ensures optimum protection for the pressure reducing valve • Several pressure zones are required when a pressurisation
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.
