EB Preventer plastic TO - serie

The Watts check valve type TO can be used, if a really strong check valve is required.
The TO is specially designed for hydraulic safety groups that are fitted to the cold water supply of storage water heaters.
This special valve is tested according to the EN1487.

It stands a maximum half hour of heavy treatment with saturated steam up to 180°C. Due to the PPS material, the TO valve will keep its form and function.
The lip-seal is mounted in such a way that it will survive the passage of high temperature steam.
