Regulation of water level, 1600

This valve controls the inflow into a basin with the help of the float and control valve. It is hydraulically/mechanically controlled. The closing speed can be regulated by the flow control valve. This prevents surges in pressure.

Application: Regulation of levels in reservoirs, pressure breaker shafts, equalising basins, etc.

Variants: Electrically controlled, with backflow prevention, with float control and combinations thereof

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)
Level control in a reservoir or pressure–breaking shaft
Level control in an equalising basin

Mode of operation
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.

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
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
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

Material
    - Basic valve EN-GJS-400
    - Epoxy coating (min. 250 µm) acc. to GSK, RAL 5012
    - Spindle unit INOX, EN-GJS-250
    - Control line, fittings and control filter stainless steel
    - control valve red bronz

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. 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.
