Tundish with Self-Closing Valve
The only combined tundish and non-return valve with a silicone membrane seal. This tundish incorporates a self-closing membrane that allows discharge to flow freely and then closes to form a seal. The membrane seal creates no resistance, ensuring smooth discharge flow from the PRV/TRV, and is spring-free, so not affected in hard water areas. When installed into a waste or soil pipe, it prevents foul odour or sewer gas from entering the building. If required, the top tundish window can be removed from the Mactun body for inspection or cleaning when maintenance work is being carried out.
