Float Valves / Float Valves for External Installation on Tanks

Float Valves for External Installation on Tanks


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 71 is a pipeline valve for tank mounting complete with tank connecting flange for direct inlet/outlet. The valve cone can be fitted with a soft seal (up to 110 °C) or a metallic seal (up to 300 °C). The valve is supplied with a ball float type SC 3 fixed to the float bar.

When enquiring or ordering please quote the suffix letters given below:
Z = inlet. Valve closes when float rises
A = outlet. Valve closes when float drops
o = upward flow
u = downward flow
r = includes sealed spindle
example: float valve Z/o (inlet valve for vertical flow upwards)
