The FVV fi ll vent valves or weigh valves can be used in bulk handling systems where product is pneumatically conveyed to a silo or hopper that is process weighed. The FVV is ideally suitable for food and chemical industries.
The valve can be used to discarge the product into a silo, while the air is exhausted. When the required weight in a silo has been reached, the valve changes position by means of two actuators. The product is then sent to alternative weigh stations or conveyed back to the main storage silo. Only one fi lter unit is required for the complete system, thus saving considerable system costs.
The FVV is available in two versions: the FVV-F type with fl ange fi ttings and the FVV-P type with pipe fi ttings. Both versions are available in aluminium, cast iron and stainless steel, in the ranges 50 - 150. Larger versions are available on request.
