The Needle Valves for Air stands for precise and reliable regulating ensuring linear regulating characteristics over the whole range of travel

Both horizontal and vertical positions of installation possible. The Needle Valves for Air are to be installed in accordance with the cast-on arrow showing the flow direction.
Reduction of sizes is possible as Needle Valves for Air are designed in accordance with the flow rate. The transition to the nominal pipe diameter may be effected by means of abrupt-extension flanges which, upon request, will be supplied by us.
Needle Valves for Air must not be used as support of the pipeline. The feet cast to the body serve as support of the valve only and not as point of anchorage of the pipeline.
On request, Needle Valves for Air are supplied with foot plate
