NV12 & 12P FLOAT VALVE
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.
The NV 12 and NV 12 P float valves are standard inlet (feed) valves for installation in tanks; they are made of cast iron. The valve cone is fitted with a soft seal.
NV 12P is fitted with a parallel guide which prevents float oscillation if a float bar guide is not fitted in the tank.
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.
