dry solids control valves

Specifically developed for use on cement and similar fine dry and dusty powders where a positive seal of the material is required above downstream equipment. The unit consists of a machined seal plate running on cam followers in UHMWPE guides through pressurised seal wipers into the product chamber which has a large void beneath the seal plate.The unit is pneumatically actuated and the plate cuts through the material flow rather than trying to compress it and prevents any further discharge of the upstream product.
