Valve design - Import export

The valve maintains downstream pressure to a constant and pre-set rate of upstream value. No pilots needed. The valve chamber is directly exposed to the downstream pressure and this varying pressure value modulates the valve to open or close according to upstream pressure.

Component to continuously unload the products in granules and powder The rotary valve is a component to continuously unload the granular or powder products from the silos, hoppers, pneumatic transport systems, filters and cyclones. The powder coming from the filter hopper or the auger fall in the unloading outlet of the valve, are moved and then unloaded in the lower part. Benefits The rotary valve was designed according to general and global application criteria. The internal rotor turns to enable continuous unloading of the two different pressure environments. Its constructions is robust and compact, access to the internal mechanical parts are easy and fast.
