Float valve with progressive control valve DN 250 PN 10/16

1601250000 Float valve with progressive control valve DN 250 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 progressive float control mechanically/hydraulically regulates the level of water in the reservoir with great accuracy to within just a few centimetres, by means of a progressive float control valve and float bulbs.

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
Size of the reservoir (water surface area)
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. 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.
