Multi-function pressure regulation valve

A flow control device comprising:

• a housing including an inlet and an outlet;
• a flow conduit disposed in the housing, wherein the inlet, the flow conduit, and the outlet define a flow passage;
• a valve seat disposed in the housing downstream of the inlet;
• a shuttle movably disposed in the housing and displaceable between a closed position engaging the valve seat to close the flow passage and an open position spaced from the valve seat to open the flow passage;
• a sealed chamber defined between the housing and the flow conduit;
• a liner fixed in the housing and positioned between the housing and the shuttle, wherein the shuttle is displaceable in the liner, wherein the shuttle comprises a first lug and a second lug, and wherein the liner comprises a downstream stop and an upstream stop, the first lug engaging the downstream stop when the shuttle is in the open position, and the second lug engaging the upstream stop when the shuttle is in the closed position;
• and
• a port coupled with a source of pressurized fluid, the port communicating with the sealed chamber, wherein the shuttle is displaceable between the closed position and the open position in a manner that is influenced by a pressure in the sealed chamber,
• wherein the port comprises a valve, and wherein the flow control device further comprises a controller communicating with the valve that is configured to displace the shuttle between the closed position and the open position.
