Diverter valve question - Vendor or valve alternatives?

Diverter valve question - Vendor or valve alternatives?

Diverter valve question - Vendor or valve alternatives?

(OP)
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.

Salina Vortex make the industry standard for dilute-phase conveying diverter valves.  

(From Memory, and it's been a while):  They don't use a ball, it's a rotary cylinder.

Unfortunetely Salina does not make an inflatable seat version.  They do not want to quote on this application

RE: Diverter valve question - Vendor or valve alternatives?



As diverter valves for special applications are difficult to find on the market, you might come better out looking for a combination of single valves.

What about knife-gate valves?


 

RE: Diverter valve question - Vendor or valve alternatives?

I was trying to have a cavity and deadleg free a path so that as much of the  water used for cleaning would be blown from the piping for rapid restart of the process. The product is a salt which would adhere at the point of moisture.

So is this feasible with knifegates?  I imagine it takes some sort of flush plate design and a special wye type fitting.  The line is 4" round tubing 11 ga, although I could  transition to square, if necessary.

Contact me, maybe I can help.
I am currently making one for a major US oilfield co.

2 posi-flate butterfly valves on a tee, if you really, really MUST have the inflatable seals.
