Page 4: Description
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 and process water supplies. Other application media only after consultation with the manufacturer. -
Page 5: Recommended Installation
If the HAWIDO 1400 is used as a safety valve the shutoff gate valve on the outlet side can be omitted. Before the installation, check that no coarse foreign objects can penetrate into the HAWIDO. -

Page 7: Venting
Venting Procedure: Slowly open the inlet gate valve on the inlet side until water flows into the valve. The valve fills with water and the air escapes through the open vent holes. When all the air has been expelled by venting the valve in the control line, re-tighten the threaded pin. Check that all the screw connections are properly sealed, and re-tighten if necessary. -
Page 8: Setting The Reaction Speed
Setting the reaction speed If the HAWIDO does not operate quietly, or if pressure shocks occur in the supply network, this can be corrected by the corresponding adjustment of the one-way flow restrictor (4). Procedure: Loosen the locknut. Screw in the set screw clockwise with a screwdriver until the valve operates quietly. -

D. Putting out of service and maintenance Putting out of service The operating valve must first be shut off hydraulically by proceeding as follows: • Slowly close the gate valves before and after the valve • Slowly close the ball valves (2A, 2B, 2C). The valve has now been taken out of operation, and a service can be carried out. -
