14. A pressure bleed-off system, comprising:
a fluid bypass line having a fluid inlet and an opposing fluid outlet, and wherein the fluid inlet is in fluid communication with a high pressure fluid injection line;
a high pressure transducer located proximate the fluid inlet;
a first plug valve residing along the fluid bypass line and proximate to the high pressure transducer;
a second plug valve residing along the fluid bypass line and proximate to the fluid outlet of the bypass line;
a first electric actuator residing on the first plug valve and configured to rotate the first plug valve between open and closed positions;
a second electric actuator residing on the second plug valve and configured to rotate the second plug valve between open and closed positions; and
a controller configured to send command signals to the first actuator to rotate the first plug valve between open and close positions and to send command signals to the second actuator to rotate the second plug valve between open and close positions, wherein the controller is configured to receive control instructions from an operator remote from the pressure bleed-off system.
