WEH Check Valve TVR2 Gas
Description

Data Sheets
The WEH TVR2 gas check valves were developed specifically as non-return protection for the installation in systems, pipelines and extraction points for gaseous media.
They offer reliable protection against return gas flow and the formation of hazardous gas mixtures.
They offer reliable protection against return gas flow and the formation of hazardous gas mixtures.
Check valves are used wherever a medium should flow in only one direction through a line and the reverse direction must be safely shut off.
The seals will not be damaged by the medium, as the valve seals are fitted outside the area of flow. The check valves therefore not only guarantee optimal sealing and minimal leakage, they also have a very long service life and are highly robust.
The minimal cracking pressure of the check valves ensures particularly low-noise operation even at high throughput rates.
Features
- High leak tightness
- Very low noise when in use due to the optimised internal gas flow
- Wear and corrosion resistant
- Robust construction
- Simple installation
