On/off valve for electrical control - closed without current DN 2" PN 10/16

1795008000 On/off valve for electrical control - closed without current DN 2" PN 10/16

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.

To use in drinking water systems (other media after consultation)
Slow, step–by–step opening or closing of a supply system by means of electrical impulses
Regulation of water levels in the reservoir (regulation of the inflow or outflow in the reservoir)
Regulation of the flow rates
Regulation of the flow rates for cooling circuits (in conjunction with a temperature switch)

The open/close valve for the electric actuation opens or closes step–by–step depending on the respective actuation of the solenoid valve. The valve closes when the solenoid valves are de–energised. The opening and closing speeds can be set on the throttle non–return valve.

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.
