EGE ecoflo-VBV V-Ball Control Valve

ecoflo-VBV V-Ball Control Valve

Brand: EGE Industrial Controls
Add Product to My Catalog

Available from size DN25 (1") up to DN300 (12"), series V-ball control valves provide a high control accuracy in a wide range of industrial applications where the process fluids contain slurries, solid particles or high fiber levels.

Thanks to its design minimizing the dead flow zones between ball and body, therefore preventing the ball from getting stuck, these valves are very popular in paper & pulp mills and mining industries where it is difficult to handle the process fluids with other standard types of control valves. Additionally, these valves can be used with any other utility application like control of steam, condensate, water, air, etc., with a high flow capacity and a high turn-down ratio due to their straight-through internal design.
Features
  • V-notch ball design
  • High flow capacity
  • Equal percentage control characteristics over a wide control range
  • PTFE or metal seated versions
  • DIN pressure classes of PN16, PN25 and PN40 or ANSI pressure classes of ANSI 150 and ANSI 300
  • Wafer type or flanged connections
  • Choice of Analog or digital positioners of regulation service
  • Optional position switches, air solenoids, lock-up valves, boosters, and other auxiliary accessories
