A flow control apparatus is disclosed which is particularly useful in liquid flow systems for blood pressure monitoring in humans and other animals. A resiliently biased valve plunger is provided with a marine bore capillary passage extending from one side of the plunger seating area to the other, thus establishing a first, low flow path. When the plunger is moved from its seat, a second, high flow path is established which flushes the apparatus. In one embodiment, the apparatus is combined with a pressure transmitting diaphragm assembly used to transmit pressure to instrumentation, the flush flow then serving to sweep air from the plenum above the diaphragm.
