Overfill Prevention Valves/Assemblies - A1100 Testable Overfill Prevention System
Emco’s A1100-T Testable Overfill Prevention Valve allows for quick and easy testing without removing the valve from the tank riser. Simply use the A0081-1100 Testing Rod to depress the test button installed on the valve, and shine a light inside the valve - if the reflective tape is visible, the valve is operational. The testable A1100-T OPV uses the same proven technology as the A1100 OPV Series. Assemblies are factory welded and 100% factory tested. Bottom tube screws to top tube/ valve assembly - No Epoxy. This saves time in the field and assures a vapor tight assembly to meet the EPA 40 CFR Part 63 requirements.
