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.
NV 98 is a float valve for horizontal installation inside a tank as inlet
valve with outlet at the bottom. This valve is made entirely of stainless
steel featuring excellent corrosion resistance. NV 98 R (spigot
connection) is fitted with a ball float, NV 98 F (flange connection) is
fitted with a cylindrical float that is adjustable on its float bar. NV 98 FP
is fitted with a parallel float guide which prevents oscillation of the
float. The valve cone is fitted with a soft seal.
The following note applies to float valves fitted with float bars: If the
liquid level is below the float bar i.e. if the float points downwards, a
guide for the float bar should be installed.
