Protection for the potable water network

WV check valves are specially designed for use in water meters and prevent processed water from accidentally being siphoned back into the potable water network. They therefore make a valuable contribution to the protection of potable water.

The installation geometry of WV check valves complies with the requirements of DIN EN 13959. In terms of form and function, they comply with DVGW standard specifications.
