Bulk material knife gate valve TYPE C for free-flowing bulk materials

Bulk Material Knife Gate Valve 

The knife gate valve for bulk solids (Type C) from AKO Armaturen is a unidirectional wafer-style valve with flange connections conform EN 1092-2 PN10. Bulk material knife gate valves are specially designed for regulating and shutting off dry and free-flowing bulk materials such as powders and granulates. Thanks to the optimum flow rate, the bulk solids slide valve is also ideal for use as a silo outlet valve. 

Bulk material slide valves in a wide variety of designs are available in nominal sizes DN 50 to DN 600. All bulk material slide valves are equipped with flushing ports on the monoblock housing to clean the cavities with air, steam or liquids.   

Available drive variants of the bulk material slides: 
Manual drives:    
  • Handwheel (with rising stem)    
  • Handwheel (with non-rising stem)    
  • Hand lever    
Pneumatic drives:    
  • Pneumatic cylinder (single-acting)   
  • Pneumatic cylinder (double-acting)   
Electric drives:   
  • Prepared for electric acutator   

Depending on the nominal width and design, bulk material slides can be configured from the following component materials: 
Body: Stainless steel 1.4408 (CF8M) or cast iron (GJL250) 
Slide plate: Stainless steel 1.4401 (AISI 316) or 1.4301 (AiSI 304)
Seat sealing:  EPDM, Nitrile, PTFE, Silicone, Viton or metallic-seated
Gland packing: braided PTFE, Graphite, ceramic fiber or synthetic fiber (PTFE-imprgnated)   

Other nominal sizes, actuator types, spare parts or accessory components are not yet available via the online store, but can be requested directly.
