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)
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.

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. Depending on the installation situation, a mounting/dismounting adapter should be provided.

Vantages

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

Caution

Dimension H1 with electric position indicator and opening limiter is 110 mm higher up to DN 100 and 130 mm higher at DN 125 to DN 300.
