Mankenberg - Float Valves Type ATHENA (NV 15e)
Valve for drinking water and high to very high flow rates
The float valve ATHENA (NV 15e) is a straight-way or angle-type single-seat feed valve with relieved cone, the cone is fitted with a soft seal. The valves are approved for the use with potable water thanks to the coating of the body in accordance with the KTW guidelines.
The valves are equipped with a float rod that is height-adjustable through the lever. Thus the fluid level can be steplessly adjusted.
Product features
Float valves automatically control liquid levels in sealed or open (non-pressurised) tanks and vessels without requiring external energy.
The float registers the liquid level and directly controls the valve via a lever.
A change in the liquid level immediately results in a changed flow volume.
