On/Off valve with float control DN 40 PN 10/16

1600040000 On/Off valve with float control DN 40 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.

The open/close valve with float protection mechanically/hydraulically regulates the water inflow in a reservoir by means of a float solenoid valve and float bulbs. The closing speed can be adjusted by means of a throttle non–return valve to prevent surges in pressure.
At inlet pressures less than 1.5 bar and more than 4 bar consultation is to be kept.

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
Available line diameters and lengths
Construction of the valve (straight or angle design)
Minimum and maximum water level (as standard between 100 and 900 mm can be adjusted using stops, greater water level differences on request)
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. If there is a free run into the water tank downstream from the valve, the slider on the outlet side can be omitted. Depending on the pressure ratios, an orifice plate should be installed on the outlet side of the valve and an opening limiter on the valve. The installation of a float protection pipe is recommended to guide the float.
