The QTP QTEC 3.5-inch bolt‑on dual electric cutout valves are supplied as a pair sized for 3.5in openings. Intended for systems needing dual control, the paired bolt‑on valves allow two electrically actuated bypasses or matched valve operation and attach to corresponding flanges or piping. Use them when larger‑diameter dual valve functionality is required in a custom exhaust setup.
