Dispense Valve Overview
The HFRL and HFRS systems will be provided exclu-
sively with MD2 dispense valves.
The MD2 dispense valve is an example of a solenoid
controlled dispense valve. When the trigger is pulled the
signal requests the dispense to start. When the machine
sees the signal, fluid rises to dispensing pressure and
the valve is opened to begin dispensing. When the trig-
ger is released, the solenoid signals that the dispense is
finished.
