Slide valves

EMDE slide valves are essential system parts.
Slide valves are deployed wherever bulk materials have to be supplied, discharged and dosed or volume flows cut off.

They are suitable for both, powdery media and coarse granulates. Needle valves are used for lumpy, highly abrasive products.

The stainless steel blade of the bulk material slide valve is mounted on steel bolts or plastic rollers, has a ground surface to prevent product baking on and is sealed all around the opening with an adjustable and full perimeter stuffing box. Gas and pressure-proof variants are possible through the use of further sealing systems such as wearless inflatable seals.
