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
