On/off valve for electrical control - open without current DN 200 PN 10

1704200000 On/off valve for electrical control - open without current DN 200 PN 10

Product attributes

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.

The open/close valve hydraulically opens or closes for the electric actuation via the solenoid valve fitted on the control line. The valve is open when the power is off. The closing speed can be adjusted by means of a throttle non–return valve to prevent surges in pressure.

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
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 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

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.
