A. Description
1. Function
The pressure relief valve maintains a pre-set inlet pressure (p1) constant. Any excess system pressure is
relieved by fast opening of the valve. The closing procedure is slow in order to avoid shock pressure loads.
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 1.5 bar to 12 bar.
Technical features:
Medium: Drinking water
Pressure stages: PN 10 (Standard DN 200 and upwards)
PN 16 (Standard up to and including DN 150)
PN 25
Flanges: Connection dimensions acc. DIN EN 1092 –2
Manometer: EN 837-1, accuracy class 1.0
Main valve material: EN-GJS-400-15
Temperature range: 2 to 40º C
2. General safety guidelines
The Hawle HAWIDO regulating valve is designed for use in drinking water supply systems. Please consult
the manufacturer before using it with other media.
Material damage or injury to persons can occur if the HAWIDO is not installed, commissioned, operated or
maintained according to these instructions or to codes of practice.
As a precondition, it is assumed that all technical regulations (e.g. SVGW, ÖVGW, DVGW...), codes of
practice (e.g. VDE, VDI ...), laws and standards are understood, and will be adhered to and applied.
Work on electrical installations (e.g. installation of magnetic position switches, solenoid valves, etc.) may only
be carried out by personnel authorised to carry out this work.
The responsibility for layout, installation position and commissioning of the fittings in the pipe work lies with
the designer, installer and/or user. Design or installation errors can adversely affect the operation of the
regulating valve and can create a significant risk. If in doubt, please consult us.

-3-
3. Recommended installation
Before the installation, all pipe work must be blown or flushed through to prevent any foreign material such
as pieces of wood, stone etc. from entering the valve.
Regulating valves are normally fitted with the valve cover upwards. It is recommended that shut-off valves be
fitted on both sides plus a dirt trap on the inlet side. Depending on the installation situation, a mounting
adapter may also be required. If the HAWIDO 1400 is used as a relief valve, the shutoff gate valve on the
outlet side can be omitted. Before commissioning, a check should be made that no coarse foreign bodies
can penetrate into the HAWIDO.
For other types of installation, please contact us for advice.

2. Preparation
Before commissioning the valve, check that the gate valves on the inlet and outlet sides of the valve are
closed and that the flange connections are correctly tightened and sealed.
On the main valve:
•Open the ball valves (2A, 2B)
•Loosen the lock nut on the one-way flow restrictor (5) and unscrew the adjusting screw by approx-10
turns. (The path to the control chamber is completely open).
•Close the ball valve (2C)
•Loosen the headless screw in the central plug on the position indicator.
•Loosen the headless screw in the male adaptor elbow union with venting

3. Venting
Proceed as follows:
Slowly open the inlet gate valve until water flows into the valve. The valve fills with water and the air escapes
via the vent holes. When the valve venting procedure has caused all the air to be expelled from the control
lines, retighten the headless screws. Check that all fittings are sealing properly and tighten if necessary.
Open the inlet valve slowly and completely.
Check:
When the outlet gate valve is opened slightly the valve should close and remain shut. Then close the gate
valve again.
If the valve does not close, the commissioning procedure must be repeated from the preceding chapter
onwards. Special care must be taken here to ensure that the upper valve chamber and control lines are
properly vented.
4. Adjustments Sustainable Pressure
The valve is prepared according to the preceding chapter. The valve is open on the inlet side and closed on
the outlet side.
Proceed as follows:
•Slowly open ball valve (2C).The valve then opens and fills the pipe work on the outlet side until a
pressure of 0.4 bar is reached. The valve then closes again.
•Gradually and slowly open the gate valve on the outlet side.
•Slowly turn the adjusting lever of the control valve (6) counter-clockwise until the valve opens
(audible sound of water flow).
•Check the inlet pressure on the pressure gauge.
•Step by step tighten the hand wheel of the control valve (6) (½ turn) according the table below.
Note:
Pause between each half turn of the adjusting lever until the hydraulic system has stabilised. Check the
pressure on the pressure gauge on the inlet side.
If the required relief or sustaining pressure has been set, tip over the adjusting lever for fixing.

5. Setting the reaction speed
If the HAWIDO does not operate quietly, or pressure surges occur in the supply network, this can be
corrected by adjustment one-way flow restrictor (5).
Procedure:
Loosen the locknut. Screw in the setting screw clockwise with a screwdriver until the valve operates quietly,
and then retighten the lock nut.
Attention:
The setting screw must always remain open by at least 3 - 5 turns; otherwise the valve will not reopen
sufficiently quickly after the closing sequence. A special setting may be required for very high inlet pressures.
6. Checking for leakages
HAWIDOs are tested for both leakage and functionality during manufacture. When checking for leakage
under operational conditions, particular attention must therefore be given to the seals of the flange
connections, the control lines and the central screw plug on the valve cover, and these must be further
tightened if necessary.

D. Putting out of service and Maintenance
1. Putting out of service
The operating valve must first be hydraulically shut off as follows:
-Slowly close the gate valves after and before the valve
-Slowly close the ball valves (2A, 2B, 2C)
The valve is taken out of operation and the maintenance can be accomplished.
2. Maintenance and Service
2.1 General
Our long experience with diaphragm valves that are controlled by the flow medium indicates that our
HAWIDOs normally function trouble-free for many years. Regular maintenance is, however, necessary to
ensure continued reliable operation.
Under normal operating conditions, the following should be carried out:
•Once a year, the valve should be checked for correct operation (function check)
•Once a year, the filters upstream of the valve and in the control lines should be cleaned
•Every four or five years, the inner working components should be checked, and worn parts replaced
(maintenance).
Under unusual operating conditions (e.g., with water that contains quantities of suspended matter, high
pressure reduction, small flow rates etc.,) maintenance should be carried out more frequently.
Maintenance label
xx stands for the year.
2.2 Annual checks
Cleaning the strainer in the main supply
•Unscrew the lid
•Clean the filter with a brush or cloth, or replace it
•Refit the filter and screw the lid back on
Cleaning the filter in the control line
•Unscrew the lid of the filter
•Clean the filter with a brush or cloth, or replace it
•Refit the filter mesh and screw the filter lid back on

-9-
Checking the valve
•Remove the position indicator from valve cover.
•Check that the valve spindle moves easily by raising and lowering it with the threaded rod.
•Install the optical position indicator.
Putting the valve back into service
•see chapter Commissioning
Checking the operation of the valve
The pressure-sustaining valve has to be set eventually in such a way for the check that the inlet pressure
permits the opening of the valve (see also the Chapter: Commissioning).
•Close the ball valve (2C) slowly; Valve must close.
•Open the ball valve (2C) slowly; Valve must open.
2.3 Four or five yearly maintenance
Cleaning the strainer in the main supply
•Unscrew the lid
•Clean the filter with a brush or cloth, or replace it
•Refit the filter and screw the lid back on
Cleaning the filter in the control line
•Unscrew the lid of the filter
•Clean the filter with a brush or cloth, or replace it
•Refit the filter mesh and screw the filter lid back on
Main valve (see chapter: Repair kits and spare parts)
•Undo the fittings of the control line and lay the complete control line aside.
•Disassemble the Optical Position Indicator and replace the gaskets
•Undo the screws of the valve cover and remove this valve cover.
•Visually inspect all inner components for wear, dirt and scaling
•Clean inner components, seat and inner surfaces including the valve cover
•Disassembly the spindle guide at the housing, rinse the housing interior.
For valves from DN 40 to DN 100 built in 2012 and DN 125 to DN 200 built in 2014, the spindle
guide has to be removed from inside of the housing. The guiding thread of the spindle and the base
valve must be extremely clean. Grease the thread well (eg Food Grease Aqua, Item No. 5292, see
chapter control line parts and accessories).
•Replace the diaphragm, the O-ring and if necessary also the seat seal
•Thinly grease the area around the spindle guide with an agent, which is suitable for contact with
foodstuffs. Check for easy movement of the spindle in the housing guide and in the cover guide.
•Assemble the main valve (See torque table in Annex). During assembly the easy movement of the
spindle must be checked several times by actuating the threaded rod.
Disassembling the control valve (see chapter: Repair kits and spare parts)
•Tip over the adjusting lever
•Turn the lever counter-clockwise until no resistance from the spring can be felt
•Remove housing screw
•Replace the diaphragm, the O-ring and if necessary also the seat seal
•Visually inspect the inner surfaces of the housing and clean if necessary, including the cover
•Assemble the control valve (See torque table in Annex).

-10-
Checking the operation of the one-way flow restrictor
•Undo the locknut
•Screw in the set screw and then unscrew it as far as it goes
•Screw in again a few turns. This process must be easy and with little resistance
Putting the valve back into service
•see chapter Commissioning
Checking the operation of the valve
The pressure-sustaining valve has to be set eventually in such a way for the check that the inlet pressure
permits the opening of the valve (see also the Chapter: Commissioning).
•Close the ball valve (2C) slowly; Valve must close.
•Open the ball valve (2C) slowly; Valve must open.
3. Repair kits and spare parts
Several spare parts are required for the four or five yearly maintenance. These can be obtained as a repair
kit for:
•the main valve
