Stem extensions and shaft extensions are indispensable for valves that are insulated or fitted with a heating jacket. They permit safe operation and automation of butterfly valves and ball valves even under difficult conditions. Our extensions are made of high-grade stainless steel or steel and are available in standard lengths as well as special versions.
The variants shown are a selection of the forms that can be produced.
In combination with AirTorque actuators and accessories – matched to stem and shaft extensions.
The required length follows from the insulation thickness plus an allowance for operation. State the valve type, stem dimension and insulation thickness and we will manufacture the extension to fit.
