3-Way Accelerator HRV-3

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.
