The HRV-3 is used to relay and accelerate hydraulic signals, making the opening and closing of large size valves significantly quicker. In response to pressure status in its control chamber, the HRV-3 directs flow and pressure between its ports in the following manner: In response to pressure applied to its control chamber, the HRV-3 connects port “0” to port “2”. In response to pressure released from its control chamber, the HRV-3 connects port “2” to port “1”. Line pressure is applied to the HRV-3 control chamber through a solenoid or other device.
