Claim 0:
1. A pressure bleed-off system, comprising:
a low pressure line having an inlet in fluid communication with a fluid injection line; a low pressure line transducer located proximate the inlet of the low pressure line;
a high pressure line also having an inlet in fluid communication with the fluid injection line;
a high pressure transducer located proximate the inlet of the high pressure line;
an outlet line placing the high pressure line in fluid communication with the low pressure line;
a fluid outlet along the outlet line;
a first high pressure line plug valve residing along the high pressure line;
a first high pressure line electric actuator residing on the first high pressure line plug valve and configured to rotate the first high pressure line plug valve between close and open positions;
a first low pressure line plug valve residing along the low pressure line;
a first low pressure line electric actuator residing on the first low pressure line plug valve and configured to rotate the first low pressure plug valve between close and open positions; and
a controller configured to send command signals to the first high pressure line electric actuator and to send command signals to the first lower pressure line electric actuator to open and close their respective plug valves, wherein the controller is configured to receive control instructions from an operator remote from the pressure bleed-off system.
