WEH® Hand Valve (Medium pressure)
Wherever the media flow within a pipe system needs to be manually shut off or opened in both directions, WEH® needle valves perform this function with absolute reliability.
The valves are extremely smooth-running and durable, as the valve needle and the rotating valve spindle are decoupled from each other. The valve needle with regulating tip and the spindle are shaped in such a way that the flow can be increased/regulated slowly and precisely when the valve is opened (6–7 turns to fully open). Alternatively, versions with a V-tip for use as a shut-off valve only are available on request (2–3 turns to fully open).
WEH® needle valves can be mounted either frontally in panels (bore diameter 6.35 mm) or laterally on rails or holders (bore diameter depending on size).
