More about this Item
WEH® Shut-off Valve TV17GR for inert gases, pneumatical actuation, with check valve, DN12, NC, 420 bar Like the TV17GO, the TV17GR linear valve is used for shutting off pressurised gas. The valve is equipped with a check valve on the outlet side. This prevents gases from flowing back into the inlet.
Due to its compact design, it is ideal for installation in gas process plants. It can also be easily integrated into existing systems.

The high pressure valves have a streamlined design that allows for top flow values and extremely low-noise operation.

TV17GR is equipped with pneumatic actuation (basic setting NC). Regular compressed air is applied to control the actuation. It is used to switch the status of the valve from closed to open and vice versa.
Compared to traditional linear valve, the WEH® TV17 valves with pneumatic actuation are characterised by their low weight.

A comprehensive range of accessories including manual and electrical output signal indicators, flow restrictors and throttle check, allows for the valves’ functionality to be enhanced at any time.

There are also various adaptors as well as welding adaptors available for the installation of the valves.
