system designed by Twiflex interfaces with the conveyor. The principle is as follows: A positive displacement pump discharges its flow through a check valve to an accumulator and is automatically switched off when the system pressure is reached. Two solenoid valves are employed, one on the flow line into the brake and one on the discharge side.
