    Abstract: A melting system includes a hopper for receiving solid hot melt material, a heated conduit in communication with the hopper for melting the solid hot melt material, and a valve for allowing solid hot melt material to flow from the hopper to the heated conduit. The valve includes a disk movable between a closed position and an open position, a stem connected to the disk and an actuator for controlling the position of the disk. The disk prevents solid hot melt material from flowing from the hopper to the conduit in the closed position and allows solid hot melt material to flow from the hopper to the conduit in the open position.

    Abstract: A pumping system comprises a pump, first and second channels, a valve, and an actuator. The pump pumps fluid according to a pumping cycle. The first channel has a first fluid flow orifice with a first diameter, while the second channel has a second fluid flow orifice with a second diameter greater than the first diameter. The valve is configured to direct fluid from the pump to the first channel in a first state, and to the second channel in a second state. The actuator is configured to switch the valve into the first state during a high pressure period of the pumping cycle, and into the second state during a low pressure period of the pumping cycle.
