Slow Closing Valve – Anti Slam – 2840 – Clean water

The slow closing valve is recommended to be installed at the air valve inlet during the filling.

The design prevents the valve from slamming when closed which can cause “water hammer” and the resultant noise and damage to piping systems.

If the liquid speed is above 3 mt per second, the water hammer and therefore the float against the seat can easily damage the valve. The same happens to deep well turbine pumps where the speed is too high and can easily exceed 3 mt. per second.

Connection : flange – DN80 to DN400

Range : PN10, PN16 et PN25
