Product Data Sheet Platon Automatic Flow Controller PLATON FLOSTAT TYPES B & LB An automatic flow control valve and governor to limit the maximum rate of liquid flow in a pipe - irrespective of pressure changes - whilst presenting the minimum resistance to normal flow. • Automatic - no power required • High accuracy - balanced control valve • Fast response - short feedback path

STANDARD SPECIFICATION Automatic Self-Acting Flow Control Valve and Governor for 2”–4” pipes (50mm–100mm) Type B units are factory set for a user defined flow rate. Type LB units control at a flow rate adjustable over a 6:1 flow range using the external hand wheel.

FLOSTAT APPLICATIONS The Flostat brings automation of fluid handling within the reach of industries requiring accurate and reliable control with a substantial cost benefit over the conventional servooperated control valve. Obvious examples of applications for the Flostat are where:- COOLING AND CONDITIONING Flostats are utilised to control the cooling water flow in air conditioning and refrigeration plant to maintain optimum efficiency. Power is not available Control setting is rarely changed Installation position is remote or dangerous It is necessary to prevent excessive flow There is a...

When placing an enquiry, please give all possible details as the manufacturers have great accumulated experience in this specialised field and could contribute valuable guidance. Certainly do not omit to specify the following:- For permanent and accurate control, it is only necessary to ensure that the available pressure does not fall below the Threshold Value which is the minimum required to provide the control force and to overcome friction losses (P1-P3). Pipe size Preferred Materials and Connections Control Setting and if adjustment required Pressure conditions upstream and downstream...
