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 55 is a single seated pipeline valve with tank connecting flange for vertical flow. The standard soft seal ensures perfect sealing of the valve.

The valves are fitted with a float bar on which a float featuring an inner tube is mounted. By changing the position of the float on the bar the required liquid level is infinitely variable.

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.

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
w = horizontal flow
o = upward flow
u = downward flow
example: float valve Z/o (inlet valve for vertical flow upwards)

» Tank connecting flange
» Float bar stainless steel
» Cylindrical float SC 8 stainless steel
» Rubber or plastic coating for corrosive media
» Various seal materials suitable for your medium
» Spindle sealed against the tank (for example with Rießler plants)
» Special versions on request

Please state working pressure range when enquiring or ordering.

Operating instructions, know how and safety instructions must be observed. The pressure has always been indicated as overpressure.
