Needle Valves are used to reduce the rate of flow in a leg of a pneumatic
circuit, consequently slowing actuator speed. Unlike a Flow
Control, a Needle Valve controls flow in both directions
(bi-directional). A finely threaded stem allows the gradual
adjustment of the amount of controlled flow passing through the
valve. Flow enters the input port, travels through an orifice sized
by the tapered stem and out the output port.
