6.1 Installation Guidelines
• Install in horizontal pipework with spring bonnet
directed upwards
• Installation in vertical pipework possible with increased
maintenance effort
• Install shut-off valves
• The installation location should be protected against
frost and be easily accessible
– Pressure gauge can be read off easily
– Simplified maintenance and cleaning
• Install downstream of the filter or strainer
– This position ensures optimum protection for the
pressure reducing valve against dirt
• Provide a straight section of pipework of at least five
times the nominal valve size after the pressure reducing
valve (in accordance with EN 806-2)
• Requires regular maintenance in accordance with
EN 806-5
6.2 Assembly instructions
1. Thoroughly flush pipework
2. Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
3. Seal in pressure gauges
