Pressure Relief
Pressu.6 outside of the metering orifice is directed to
the bonom ot the flow control valve. When the pressure
builds up, the reliet valve in the flow control valve opens
to relieve the pressure. As the flow control valve is

the pressure outside the metering orifice. The above
operations are repeated to provide constant discharge
