4. Recommended Installation of Valves with Floater
Recommended installation
Prior to the installation of the valve, all the pipework must be purged carefully, to prevent the entry of any
foreign bodies, such as pieces of wood, stones etc., in the control valve.
Inlet pressures from 1.5 to 4 bar the
Hawido floating valve type 1600 can be
used together with a opening limiter.
If the inlet pressure is between 4 to 9
bar, an orifice is required after the
Hawido valve. The pressure will be
reduced in two steps.
If the pressure is between 9 to 16 bar, a
Hawido pressure reducing valve is
required before the floating valve.
The HAWIDO must be installed horizontally, with the valve cover facing upwards. We recommend the fitting
of a shut-off valve and a dirt trap upstream of the valve. Prior to commissioning, a check must be made to
ensure that no coarse foreign bodies can enter the HAWIDO.
For other types of installation, please contact us for advice.
