sonnax valve body reaming fixtureSonnax Valve Body Reaming Fixture VB FIX Repairing worn valve bores can be nearly impossible on some valve bodies due to the lack of a pilot point for reamers. Instead of replacing the entire valve body, the patented Sonnax VB FIX valve body reaming fixture offers a reliable solution. This self aligning system creates a rigid, external guide for the reamer and alignment pin, making it possible to recondition bores with consistent, accurate results.
