Diaphragm valve 1500 series

hydraulically-operatedpressure-reducingfor water

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) Reduction in pressure to supply the network Emergency feed into a second network (network connections) Mode of operation The pressure reducing valve reduces a variable inlet pressure to a constant outlet pressure. Fluctuating inlet pressure and flow rate have no effect on the outlet pressure controlled by the control valve. The outlet pressure is adjustable in the range from 1.5 to 12 bar (standard design). 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) Desired outlet pressure Maximum and minimum flow rates Possible requirement for extinguishing water 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.
