Clear Action Gate Schuifafsluiter

Pneumatische & vrije val transport systemen

Clear Action Gate schuifafsluiter van Vortex Valves voor het regelen of afsluiten van de droge stof productstroom in een pneumatisch transport systemen met een werkdruk tot 1 bar. Geen buiten liggende bewegende delen. Vierkante doorlaat met ronde inlaat en ronde uitlaat voorzien van flenzen. Ideaal voor applicaties met vettige en kleverige producten als cacoa, suiker of melkpoeders. Mechanisch zelfreinigend na elke cyclus. Schakelen in productstroom. Gas en productdicht naar de afgesloten zijde en naar buiten. Afdichtingen liggen uit de productstroom. Uitwisselbare slijtdelen, afdichting kan na-gesteld worden zonder de schuifafsluiter uit het systeem te halen. Atex volgens EC richtlijn 94/9/EC zone 20. Harde polymeren afdichtingen volgens EG richtlijn EG1935/2004.

Traditional valves rely on soft rubber seals or packing for sealing. Rubber seals can erode or tear away in service and bonnet packing can “relax” allowing leakage necessitating frequent maintenance. The Clear Action Gate eliminates these problems by using “live” loaded hard polymer seals which compensate for wear, to maintain contact with the stainless steel blade.
Conventional round end blade knife gates and butterfly valves wedge material in the seal area which prevents positive shut off of material and air, causing excessive valve wear, material degradation and valve binding. The machined square edged blade of the Clear Action Gate mechanically “clears” the materials from the sealing surfaces on each closing cycle allowing materials to discharge beneath the valve. Open cavities where materials collect in traditional knife gate valves have been eliminated with the square blade and seal design.
The aluminum frame and body provide for light weight and corrosion resistance. The stainless steel gate internals, and hard polymer seals provide corrosion and wear resistance making this valve an excellent choice in handling food, plastics and fine minerals in applications up to 250 F. In demanding service applications the external seals can be replaced without removing the gate from service.
