A. Description Function Note functional diagram on p. 4. The stepwise working on/off valve for electrical control opens or closes hydraulically, as long one of the two electric solenoid valves (5A, 5B) is energised. The HAWIDO – valve (1) remains closed when there is no voltage to the electric solenoid valves.
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.
B. Commissioning Functional diagram (1795) Components Main valve 1200 Ball valve (A, B, C) Filter One-way flow restrictor (A, B) Solenoid valve (A, B) Pressure gauge with ball valve Optical position indicator (optional) Electrical position indicator (optional) analogue position indicator (optional) Valve opening limiter (optional) Preparatory work 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 have been correctly tightened and sealed.
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 (4A and 4B). Strongly throttled one-way flow restrictors (4A and 4B) permit longer impulse times (contact the Hawle Company for basic settings of impulse and pause lengths).
Loud noise Unfavourable operating Change pressure by approx. 0.1 conditions to 0.2 bar. Slightly open or close the one-way flow restrictor. Contact the Hawle Customer Service department. Wrong valve size Have the correct valve size calculated (contact Hawle) Erratic operation...
D. Putting out of service and maintenance Putting out of service Comment: Electrical work may only be carried out by qualified technical personnel. Power must be removed from the solenoid valves The valve closes. Then: • Slowly close the gate valves before and after the valve •...
• Checking the valve • Remove the vent plug or assembled accessories from the valve cover. • Check that the valve spindle moves easily by raising and lowering it with the threaded rod. Special attention must be paid to this test procedure, above all with valves with modified counter seats. Putting back into service •...
Putting back into service • see Commissioning chapter Functional check of the valve • The function of the valve can be checked by actuating the solenoid valves (according to table in section Principle of operation). Repair kits and spare parts Several replacement parts are required for the 4 or 5 - year service.
