Water pressure relief valve 1400 series

hydraulically-operatedstandardflange

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) Sustaining the network pressure in a supply Protecting the network by releasing excess pressure Mode of operation The pressure relief valve maintains constant the pre-set inlet pressure (p1). Any excess system pressure is relieved by fast opening of the valve. The closing procedure is slow in order to avoid shock pressure loads. Variable flow rates have no effect on the maintained pressure which is regulated by the control valve. The overpressure or maintained pressure can be set within the range of 2 bar to 16 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) Required sustained pressure or dischargepressure Maximum and minimum flow rates 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.
