Flow control valve handles pressure
variations
The Platon Flostat is an automatic flow control valve that regulates gas or liquid flow in a pipeline to a preset value, despite typical line pressure variations.

The Flowbits catalogue presents the company's Platon ranges in detail, with accessories like spare tubes, fine control valves and electronic alarms.
Sensor monitors 1-200bar pressures
The Sensit Economic Industrial Transmitter incorporates an ASIC circuit to ensure accuracy and temperature compensation across all environmental conditions.
The Flostat is a purely mechanical flow controller, no power or external input is needed.
It is therefore suitable for hazardous liquids, and is totally, intrinsically safe.
The operator adjusts the flow rate to the desired setting using a hand wheel, which can be supplied with an indicator on the larger type FV models.
Automatic flow regulation is then achieved mechanically using a pressure differential developed by the flow to balance with the constant force supplied by an internal spring.
With a fast response time, the Flostat is ideal for regulating the correct gas flows through laboratory systems where the source supply insufficiently regulated, or from a manifold supplying several different users.
With liquids, the Flostat can overcome the flow variations resulting from changes in tank levels, or from pump performance variations.
Platon Flostats Type MN and Type FV are available with brass or stainless steel body materials.
Type MN units are suitable for the lowest of flow rates, and can be directly coupled to Platon G Series glass tube variable area flowmeters, also available from Roxspur Measurement + Control, providing multiple-turn control of flow regulation and indication, particularly for laboratory use.
At higher flows, Type FV Flostats are suitable for 0.5 or 0.75in line sizes at flows up to 13 litre/min of liquid, or 400 litre/min air equivalent at ATP.
Further models and options are available, for example units with calibrated scales, or for higher flow rates in line sizes up to 4in.
The Platon Flostat will be on display on the Roxspur Measurement and Control stand at the Mtec Exhibition at the NEC Birmingham on 15th and 16th February 2006.
