Flow control valve handles pressure variations

A Roxspur Measurement and Control product story

Edited by the Engineeringtalk editorial team Jan 19, 2006

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 Platon Flostat from Roxspur Measurement and Control is an automatic flow control valve.

It regulates gas or liquid flow in a pipeline to a preset value, despite the typical line pressure variations that would affect flow through a preset control valve adjustment.

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.
