NEW Cone valve K5 and K6 for bulk materials Pneumatically operated cone valve for closing of pressure vessels. Sealing is carried out by means of a conical seal which is pressed against a seat ring by means of a pneumatic rotary drive. The overpressure in the pressure vessel also backs up the sealing process. The abrasion on the sealing surfaces is automatically counterbalanced to a certain degree by means of the closing device. Both the conical seal and the seat ring can be replaced individually. The cone valve has a much longer service life than a butterfly valve when used with abrasive products. Areas of application: • Inlet closure for pneumatic pressure vessel conveyor • Shut-off valve • Particularly suitable for abrasive bulk materials, e.g. cement, fly ash, sand, aluminium oxide etc. • Replacement of conventional butterfly valve for a longer service life Advantages: • Optimised product flow thanks to steep angle of the cone • Compact design • Closes against full product flow (depending on product) • High throughput (depending on product): DN 200: 15 – 50 m3/h DN 300: 40 – 120 m3/h DN 400: 70 – 210 m3/h • Minor wear • Adjustable opening • Compact dimensions • Self-cleaning sealing surface • Installation possible at a later date Brochure No. 649_en
