Anybody know of a suitable valve?

11/22/2007 12:34 PM

Does anybody know of a valve that can regulate gases [air] operating under the following conditions?

A one-way valve under 1-22 Bar pressure on the 'in side' and 1-100 Bar pressure on the 'out [non-return] side' operating at temperatures between 10-1500°C on the 'in side' and 10-6200° C on the 'out side'. Opening and closing up to 10,000 times per minute [167 x/sec]

The volume of gases [air] passing through the valves per operation would be in the region of 750 cubic centimetres.

I am thinking of a 'pea' type valve but could a tiny ceramics sphere withstand 10,000 operations per minute 24 hours a day? What size 'pea' would be required for the minimum disturbance of gas flow? Is there an off-the-shelf valve available? Is there an alternative?

I look forward to reading your words of wisdom soon

Regards, Jon London

This sounds more like a pressure intensifier than a regulator if you want to increase the pressure from 22 bar inlet to 100 bar outlet

<6200° C on the 'out side'>

Is that a typo? It's well over the melting point of tungsten.
