Needle valves

For shut-off and control of fluids
Rötelmann needle valves feature a two-part construction with a threaded body and a precision spindle. The spindle has integrated vertical detends and an easy to operate aluminium knob. The three-coloured scale allows settings to be easily repeated. Flow settings can be fixed with the set screw in the knob. Because of the design, Roetelmann needle valves are ideal for panel mounting.
