Dosing screws with overhead valves
Dosing screws with overhead valves are highly suitable for accurate dosing without caving. By fitting the dosing screws with overhead valves with bearings on one side, you get the possibility to produce an axial outlet that can be pneumatically closed by a valve. The use of dosing screws with overhead valves is also not unusual in an overpressure or under pressure situation. Dosing screws with overhead valves can be produced in various materials to the client’s specification.
Diameters from Ø50 to Ø485 are available, with capacities from 0 to 20,000 litres per hour.
Dosing screws with overhead valves are used in the following industries:
Foodstuffs, Chemicals, Pharmaceuticals, Biomass, Plastics, Paper, Pet food, Cement, Sugar and many others.
