Needle valves create a means of controlling the flow of liquids or gases through the valve mechanism. It is possible to easily adjust the flow rate to any specific amount desired, making the needle valve useful in a number of applications. Parker's all brass needle valves have metal-to-metal seats with fine thread screwdown making them ideal for situations in which the desired flow must be maintained with little to no variance. By controlling the needle valve rate, stress on the delivery system is kept to a minimum. The specialty formulated low temperature seal in the Parker needle valve remains elastic to temperatures as low as -40°F.  
Parker's needle valves should always be installed with the pressure against the seat.
