Inquiry (采购产品): Hot gas shut off valve I need a small valve (1/4")that will be able to work in hot helium (500°C) at pressures up to 90 bar. The valve must automatically shut when gas temperatures through valve exceeds 500°C. Normally there will be very little or no flow, as I will beusing these valves for pressure gauge instrument valves. The valve should be totally mechanically operated, with no electrical power.
