They have experience dealing with applicaitons like this. ■

From their web site ---

Bulk Material Valve Specifications

U.S. Patent 5,396,919 Standard Design

Seats & Discs Cast 440 C Stainless Steel, hardened

Temperature range 450°f; Carbon Steel 550°f; special design 750°f

Significantly short of 1700 deg F ■

It would be the process valve for this application. Their engineering staff would have to look at the specifics of the application on this one. Obviously they would need exotic alloys for this application, but that is the beauty of this valve. It is a fabricated design so they can make it of just about any workable metal. ■

True, but 1700 deg F is still red hot. ■

Hello Joseph,

please advise the following so we might send you a quotation.

the size of gate required

mode of operation, air cylinder, motorized etc.

pressure above and below the slide valve

description of the material to be handled

Thank you ■

had a lot of experience with these on a blast furnace dust catcher. Look at a clyde dome valve or look at an everlasting valve (that's the name of the company - everlasting valve company). Both of these have performed better, but they will be more expensive.
