Diaphragm valve 1700 series

electrically-operatedhydraulically-operatedflow control

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) Opening or closing a supply system by means of an electrical signal Mode of operation The open/close valve hydraulically opens or closes for the electric actuation via the solenoid valve fitted on the control line. The valve is shut when the power is off. The closing speed can be adjusted by means of a throttle non–return valve to prevent surges in pressure. 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 of the reservoir Required flow rate Maximum permissible loss of pressure Voltage information for the solenoid valve 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.
