Low
Leak Slide Gates
are primarily used for isolation purposes where low
levels of leakage and pressure drop are required. Low
Leak applications include isolation for systems that
function under negative pressure or require a tight
shut off to aid in the systems process. (i.e.shaking
the bags in a large bag house) |

Zero
Leak Slide Gates
are used when man-safe isolation is required. Man-safe
isolation is accomplished by pressurizing the seal air
chamber that surrounds the blade edges. When compared
to a double louver, the zero leak slide gate requires
less seal air and flange to flange space; therefore,
it can be used in tight runs of ductwork.
