ABSTRACT:
A normally closed valve system for sealing off low pressure gas flow through a pipe. The valve comprises an inflatable bladder which blocks relatively low pressure flow through the pipe and permits relatively high pressure flow through the pipe. In one form, the invention comprises a fail-safe bypass monitor and method for measuring air inleakage in a steam turbine. The monitor selectably bypasses low volumetric flow rates from a pipe for measurement and admits flow through the pipe whenever the flow rate exceeds a predetermined value.
