Round Valve Extension Stems


Round Valve Extension Stems

ROUND VALVE EXTENSION STEMS are used to raise the elevation of both buried and “in-plant” valves having a 2" square operating nut. We can adapt to valves without 2" nut.



Overview


The extension stem is made up of an extension rod (or pipe), a 2" square top wrench nut (or handwheel), and a bottom wrench nut coupling. The wrench nut coupling fits over the 2" square nut of the valve stem being raised and is held to the nut by a set screw threaded in the bottom coupling.

The top nut (or handwheel) and bottom coupling are pinned to the extension rod (or pipe) which is drilled to receive stainless steel spring pins. The top nuts and bottom couplings are available in either ductile iron, grade 65-45-12, or stainless steel, Type 316. The pinned connections permit the removal of the castings so the rod can slide through Trumbull floor boxes and stem guides. Extensions can easily be shortened by cutting the stem & re-drilling for the pin.

Extension stems are normally furnished complete with rod, coupling, top nut (or handwheel), set screw and pins; however, top nuts and bottom couplings are also available for separate sale. Universal joints, thrust collars & miter gears are also available.
