1850 Float Nose

The WellMark Float Nose is an inexpensive mechanical lever control that provides convenient vessel access. The 7″ x 12″ float provides sufficient lift torque to operate WellMark’s near-balanced 1250 Series lever valve as well as other industry balanced valves. The float nose is widely used as an oil or water dump control on separators, water knockouts, horizontal emulsion treaters, and other similar accumulators.
