    Floating seat Ball Valves - Low pressure air

    Hi Guys We are having quite a big engineering problem where 1/2" and 3/4" bore floating seat(Teflon) ball valves are seizing and also leaking when dry air at 60cm of water pressure (0.06 bar approx) is being sent though it. These ball valves are actuated using a pneumatically controlled head...
