What types of manual and electric valves should be used in the pipelines for edible starch dispersions?
Thread Content
May I ask, after mixing edible starch with water in a ratio of about 1:3 in a mixing tank to form a suspension, and then transporting it using a pump, what type of valve should be used in the pipelines – gate valves, ball valves, or some other type? Additionally, what type of valve should be used in pipelines with starch-based glue (with a viscosity of about 10,000 centipoise)? I seek advice from experts.
When I was at the winery before, starch was mixed with warm water to form a slurry, which was then pumped into the reaction vessels. The valves used in the pipelines were stainless steel butterfly valves, with a pipe diameter of Dn80. There have been no problems using it.
Both ball valves and butterfly valves can be used. For diameters over 100, butterfly valves are a cost-effective choice; ball valves are more reliable for smaller diameters
Thank you all for your advice. The diameter of these delivery pipelines is DN100 and DN80; if ball valves are used, could there be severe wear?
Hello, although you haven’t provided detailed information on other parameters for this process, it is certain that the powder medium inside will cause wear to the seal of the ball valve. The service life of this ball valve depends on the frequency at which it is opened and closed. If the switch is used frequently, this ball valve will definitely wear out quickly. Our company’s coaxial valves are designed specifically for use in such applications. It allows media containing impurities (metal shavings, coal dust, alloy powder, flour, etc.) to pass through, and is used in various machine tool factories, cleaning machine manufacturers, and the coal dust blowing industry.
