The Capital Controls® vacuum regulator is a spring-opposed diaphragm type design which serves, via the throttling action of the inlet valve, to reduce the gas from a varying supply pressure to a constantly regulated vacuum. This allows for safe transport of gas to the point or points of application.
The vacuum regulator has a vacuum sealing o-ring which stops the gas flow in the event the operating vacuum becomes excessive. This condition can be caused when the supply of gas is exhausted, or when the gas supply valve(s) is closed during ejector operation.
The vacuum regulator is equipped with a gas pressure gauge to provide a local indication of the gas supply status.
