If flow is opened to the filling valve of this type, water enters the inlet area and the increasing pressure opens the valve so that water in the outlet area can flow into the container. If the water level in the container reaches the preset level, then the float valve closes. The following are some typical applications: · · · · · · · · Potable water supplies, for example water reservoirs etc. Swimming pools Firefighting systems - sprinkler installations Ship construction (fire tenders) Watering systems in market gardens and in agriculture Water supply networks in large building developments (eg. high rise blocks) Mining applications Gravel pits, concrete mixing plants etc. Flow Diagram [l/s] 1000 500 1000 500 100 50 100 50 10 5 10 5 1 1 0, 01 0, 05 0, 1 0, 5 1 5 10 [m3/h] 5000 EN0H-1328GE23 R1009 · Subject to change DN 450 DN 400 DN 350 DN 300 DN 250 DN 200 DN 150 DN 100 DN 80 DN 65 DN 50 [bar] www. honeywell. com 53 FV300 Filling valve Spare Parts Filling valve FV300, from 2002 onwards 2 No. Description 1 Pilot float valve Level switching differential 5 - 160 cm 3 1 3 2 Pilot float valve Level switching differential 5 - 40 cm Set of seals DN 50 DN 65 DN 80 DN 100 DN 150 DN 200 DN 250 DN 300 DN 350 DN 400 DN 450 0903750 0903751 0903752 0903753 0903754 0903755 0903756 0903757 0903758 0903759 0903760 DN 50 - 450 70-610 Dimension DN 50 - 450 Part No. [. . . ] 70-550 3 3 3 3 Automation and Control Solutions Honeywell GmbH Hardhofweg D-74821 Mosbach Phone: (49) 6261 810 Fax: (49) 6261 81309 http://europe. hbc. honeywell. com www. honeywell. com Manufactured for and on behalf of the Environmental and Combustion Controls Division of Honeywell Technologies Sàrl, Rolle, Z.
