Physical characteristics

The main valve is a hydraulically operating diaphragm valve. The work energy is the inherent medium.
Most valve types operate purely hydraulically without any foreign energy.

Application

To use in drinking water systems (other media after consultation)
Prevention of backflow into the supply system
Can be used, above all else, in combination with other valve functions

Mode of operation

The backflow prevention valve hydraulically prevents any backflow, when the inlet pressure is lower that the outlet pressure. The opening and closing speeds can be set on the throttle non–return valve.

Product information

To calculate the dimensions of the valve please refer to the following information:
Maximum and minimum inlet pressure (static and dynamic pressure ratios)
Existing counterpressure
Maximum permissible loss of pressure
Available line diameters and lengths
Construction of the valve (straight or angle design)
For the calculation basis, information on the loss of pressure and the characteristic values of the valve, please refer to the end of Chapter E.

Design

Design according to DIN EN 1074
Construction length acc. to DIN EN 558
Flange mass according to DIN 1092-2, to PN 25 DN 300
Pressure levels: PN 10 or PN 16 to DN 300, PN 25 to DN 200, higher pressures on request.
Nominal widths DN 50, DN 80, DN 100 and DN 150 available in angular design
Nominal widths 1 ½" and 2" with threaded connection (female thread)
Medium temperature up to 40°C

Installation and assembly

Shut–off valves should be fitted on both sides of the valve and a dirt trap should be installed on the inlet side of the valve.

Vantages

Maintenance-free, non-rusting valve seat
Pressed-in seat
EWS-coating according to RAL GSK
