Wawcon’s telescoping valves are made to fit your needs. You may want a bell or a square shape at the top, those are not a problem. Our slip tubes lift stems and lift pedestals are usually all stainless steel. The receiver pipe can be galvanized steel, stainless steel or ductile iron, as needed.
These valves are typically used as a decant mechanism in digesters, whether it is used with an “airlift” or into a drain pipe.
