Who makes an inflatable seal tubular diverter valve for solids handling. So far I have only been able to find Zeppelin, a German Mfg co. Any USA companies a little closer?

As an alternative are there any multiport ball valves that might work? Cycling is only 1/month. T= 200 F max. Pr nomrally 6 psi 30 psi water used for cleaning. Cleaning washes out a solids buildup from dilute phase conveying.

Although the valve will not be actuated while water is under pressure, some salt water will get behind a ball and dry out. The concern is solids forming from evaporation, or powder that would work behind the ball, might seize it or score the seat/sealing surface when actuated the next time. ■
