NV71 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.
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.

- o = upward flow
