Vo-Tech CNC Modular Boring Bar Systems are fully automated, single-setup tooling platforms for the in-situ refurbishment of large industrial valves — anchored by the MSIV Repair Tool, an INPO-recognized system that has eliminated MSIV LLRT failures at the plants where it has been deployed. The product family extends the same proven architecture to F-032 control valves and RHR valves, consolidating inspection, machining, welding, and finishing operations into one fixed setup that reduces outage duration, personnel exposure, and total repair cost.
Vo-Tech Vertical Motor and Pump Coupling Alignment Tools deliver fast, precise, and safe alignment of vertical motor and pump coupling assemblies in heavy industrial environments. Each tool eliminates the need to rotate heavy motor shafts and couplings during alignment — improving safety, reducing physical strain on personnel, and shortening maintenance windows.
High-precision ball bearings allow the tool to rotate smoothly against the motor coupling while a dial indicator captures the position of the pump coupling. Technicians can identify misalignment immediately and make precise adjustments until the assembly is in tolerance. Available in four configurations, the toolset covers a full range of coupling sizes, equipment layouts, clearance constraints, and accuracy requirements.
Vo-Tech Nut Runners are purpose-built tools used to remove and capture bottom nuts and washers from reactor dome studs during reactor head disassembly. Available in pneumatic and electric configurations, both tools allow nuclear workers to perform critical disassembly tasks from a safer distance from the radiation source — improving outage efficiency while reducing personnel exposure in areas where manual access is restricted or unsafe.
Vo-Tech designs and manufactures engineered training mockups that replicate reactor components, valve assemblies, and specialty equipment with full operational fidelity. Built for procedure validation, crew training, and tool qualification, each mockup gives nuclear and industrial customers a controlled environment to prepare critical work — improving outage performance, reducing field exposure, and increasing first-pass success at the work face.
The Vo-Tech Stud Removal Machine is a portable, precision tool engineered for on-site removal of broken, seized, or sheared studs without damaging the threaded hole. Used across nuclear, power generation, refining, and heavy industrial applications, the machine drills and bores studs out through controlled machining — recovering threaded holes that traditional extraction methods would damage or destroy.
The Vo-Tech Stud Hole Cleaning Machine is a purpose-built tool for cleaning the threaded stud holes in reactor vessel head flanges during refueling outages. A rotating nylon brush head and integrated vacuum attachment remove dried anti-seize residue thoroughly while protecting thread geometry and capturing debris at the source — supporting reliable stud reinstallation and reducing contamination risk during reactor head reassembly.
The Vo-Tech Stud Lifting Wrench is a purpose-built mechanical lifting tool that safely raises reactor dome studs into their locking position during reactor head disassembly. Replacing manual lifting — historically a source of worker injuries and OSHA-recordable incidents — the tool provides a controlled, repeatable method for clearing the work area for reactor dome staging while protecting personnel from strain and impact injuries.
