A. Description
1. Function
Note functional diagram on p. 4.
1. Reduces a variable inlet pressure (p1) to a lower and constant outlet pressure (p2) with a pressure
reducing valve (6). Fluctuating flow rate and inlet pressure have no effect on the outlet pressure
controlled by the control valve. The outlet pressure (p2) is adjustable in the range from 1.5 to 12 bar
(standard).
2. Maintains a minimal inlet pressure by means of a pressure relief valve (10). Variable flow rates have
no effect on the maintained pressure which is regulated by the control valve. The overpressure or
maintained pressure of the standard version can be set within the range of 2 bar to 16 bar.
3. Prevents any backflow when the inlet pressure (p1) is lower than the outlet pressure (p2).

2. General safety instructions
These instructions must be read through carefully and understood before starting the commissioning.
Damage to property and injuries to persons could occur as a result of improper installation, commissioning,
operation and maintenance.
The Hawle regulating valve (HAWIDO) has been designed for use in drinking water supplies.
Other application media only after consultation with the manufacturer.
The technical regulations (e.g. SVGW, ÖVGW, DVGW...) and codes of practice (e.g. VDE, VDI ...), laws and
standards are taken as a minimum standard, and must be adhered to and applied.
Work on electrical installations (e.g. installation of electrical position indicators, solenoid valves, etc.) may
only be carried out by personnel authorised for this work.
In principle, the responsibility for the layout, the installation position, the installation and the commissioning of
the fittings in the pipe work lies with the designer, the installation company and/or the operator. Design or
installation errors can adversely affect the safe operation of the regulating valve, and can represent a
significant risk. Please consult us in case of doubt.
