Outlet valves - Import export

The valve isolates pumps from the system during pumps starting and stopping to protect pipe lines and pumps itself. The valve is equipped with a control solenoid valve that is switched on at pump starting and is able to fulfill pipe line gradually, reducing pressure rising peaks and allowing soft starting of the pump with closed outlet. The valve controls pump stopping as well, gradually closing before sending a closing signal to the pump. In case of casual pump stop, the valve acts also as an automatic check valve, preventing backflow over the impeller.

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.
