Parts Desk Insights
Best Use Case: Use this valve when you need a 3-way, full-flow shutoff/selector style control with a positive “off” center position for marine fuel lines.
Common Issues: If a valve is difficult to move or doesn’t hold position, check for misalignment at the mating connections and verify that the handle is able to travel through the full 180° rotation without interference. Also inspect the valve’s sealing surfaces and ensure the correct mating parts/gaskets are installed for your installation.
