WEH® Shut-off Valve TV17GOS
The WEH® TV17 Shut-off valve for oxygen is used to shut off the flow in oxygen systems. Due to its compact design, it is ideal for installation in technical gas plants. It can also be installed in existing systems without any problems.
Thanks to its streamlined design, the shut-off valve impresses with high flow values and its extremely low-noise operation.
The WEH® TV17 Shut-off is available with manual or pneumatic actuation (initial position NC or NO).
