The WEH® TV17GO Shut-off valve for inert gases is used to shut off gases under high pressure. 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® TV17GO is available with manual or pneumatic actuation (initial position NC or NO).
