Abstract: A valve slidably disposed within a bore and movable between first and second positions to control application of a source of fluid under pressure between an inlet and outlet port. An electrically operated torque motor is connected to the valve to drive the valve in response to an electrical signal applied to the torque motor. The valve is connected to a system and is responsive to a discrepancy between a control and monitor section of the system to effectively lock the system in a failure indicating mode of operation.
