Stem extensions are valve handle extensions, designed for use on valves located areas where standard configuration valve handles are inaccessible. They provide a direct connection between the actual valve stem and the relocated valve handle. Single piece stem extensions attach direct to the valve stem and the moving stem is exposed. Two-piece stem extensions consist of not only the single piece stem extension, but are also provided with an outer housing. The outer housing acts an outer sleeve which fits over the inner stem extension protecting the moving inner stem extension in buried applications. Support brackets and plates are typically used with both types of extensions. They provide a strong anchoring point for heavy gear-operators on butterfly valves, or prevent lateral movement on single piece lever handle extensions.

A 2" square operating nut is designed to be installed directly to valve stem or valve stem extension. Permits opening and closing of valves in out of reach locations using an industry standard extended T-bar wrench or key. Typically used in below grade installations, the 2" square operating nut is an industry standard accessory that can be installed on most quarter turn and multi-turn valves.

A chain operator is designed to be used for operating a valve in an overhead location. The chain operator attaches to a valve handwheel and a looped chain is fed thru one side of the operator and out the other. By pulling on the chain, the valve handle is turned to either open or close the valve.
