Spherical Disc Valve High Performance Butterfly Valve

Precise & Strong Durable to 240 °C / 600 °C Temperature and 10 Kg/cm2 / 20 Kg/cm2 Pressure

5 Special Effects.

  • Compact Design – Full Port – Offers Mass Flow
  • Simple Structure, Light & Smooth – Takes Very Short Time For Opening & Closing With Very Low Torque
  • Easy Maintenance – Replaceable Seals Design
  • Self Sealing – Self Cleaning The Under Cut Disc Segment And Seal Tends To Wipe Away The Material Form The Sealing Area,
  • Gland Pressing Plate – Ensure Compete Utilization of Gland Seals

Application

  • Hygienic Powder & Slurries, especially in Pharmaceutical Industries.
  • Chemical and Dyeing Fluids in Textile Processing Brine Waters & Oils.
  • Steam Lines, Air / Gas Lines / Vacuum.

Spherical Disc Valve has been Proved as Superior to Other Valves in Many Aspects, Particularly in…

  • Weight
  • Space
  • Pressure Range
  • Multiple Operations
  • Maintenance Ease
  • Torque & Economy
