Needle valves are used to control flow in both directions. A finely threaded stem allows gradual adjustment of the amount of controlled flow passing through the valve. Air enters the input port, travels through an orifice sized by the tapered stem and out the output port. When flowing in the opposite direction, air travels back through the orifice and out the input port. To match system requirements, Pneumadyne needle valves are offered in a variety of configurations with several flow rate... (read more)Browse Control Valves Datasheets for Pneumadyne, Inc. -
The fine threads of the needle valve permit excellent adjustment for precise control of flow. The flow is restricted in both directions and is adjustable from 0 to the equivalent flow of a 0.025" diameter orifice.
