Fluid control valve actuating system
A control system adapted to control an actuator between extended and retracted positions has a fluid control valve connected to the actuator a source of high pressure fluid and a reservoir. The fluid control valve is movable between a first position at which the actuator is connected back to the fluid reservoir adapted and a second position operable to connect the actuator to a high pressure actuation fluid source. An electronic control module is connected in control communication with the fluid control valve and adapted to automatically generate a control signal to position the control valve at the second position in response to an elapsed time being passed at which the fluid control valve is at the first position is greater than a predetermined time.
