A pharmaceutical filler apparatus (20) is disclosed. The pharmaceutical filler apparatus (20) cooperates with a conveyor (22) conveying containers to position each of the containers proximate a fluid delivery conduit (36) for receipt of fluid. The present invention further includes a reservoir (42) positioned above the containers at a predetermined height, the fluid being maintained in the reservoir at a constant level. The pharmaceutical apparatus (20) further includes a quick acting pinch valve (50) associated with the fluid delivery (36) for opening and closing the fluid delivery conduit (36). The pinch valve apparatus (50) includes a biasing spring (98) for biasing a valve apparatus (50) into a first position whereby the fluid delivery conduit (36) is closed. A cam actuator apparatus (54) cooperates with the pinch valve apparatus (50) to position the pinch valve (50) in a second position whereby the fluid delivery conduit (36) is opened. A timing means monitors the amount of fluid delivered into the container and activates a solenoid apparatus ( 62) thereby releasing the pinch valve apparatus (50) from its second position where it is releasably retained, whereby the pinch valve apparatus (50) substantially instantaneously moved into the first position to close the fluid delivery conduit (36).
