BI-TORQ® Valve Automation designs and manufactures custom extensions for buried service, heat insulation, tank mounts and submerged valve applications where the valve handwheel, gear operator or actuator must be extended for operator accessibility. A mounting bracket complete with thrust bearing is furnished to carry the weight of the extension and eliminate load on the valve stem. All extensions over three feet are supplied with universal couplings to compensate for misalignment at installation. One additional mounting bracket is provided at the top of the extension for the operator plus one stabilizing bracket per six feet of extension.

Additional Information

Buried Service Extensions

Buried service extensions are ideal for applications where the valve is located either below ground or in a tank where the operator is not readily accessible. These extensions are available in carbon steel or stainless steel construction.

Heat Extensions

Heat extensions are designed to protect an electric or pneumatic actuator and its related accessories by preventing heat transfer from the valve. All heat extensions include high temperature epoxy paint and vent holes for both the bracket and coupler.
