Industrial applications

  1. Body Streamlined design and smooth finish of the body provides minimum resistance to flow.
  2. Disc Streamlined and low profiled disc ensuring higher Cv values. Double offset disc design reduces seal wear and torque.
  3. Sealing System Sealing on seat face is ensured by an endless T profile resilient sealing ring, which is held on the periphery of the disc by a retaining ring. In closed position of disc the resilient sealing ring is pressed against the cone shaped seat face of the body and provide safe sealing in either direction of flow. In opened position of disc, sealing ring is completely unstressed due to the double eccentric disc design. One piece retaining ring prevents sealing ring from rolling out. Sealing ring can be replaced easily at site without dismantling the valve disc and without any special tool requirement.
  4. Shafts Stub shaft design provides small restriction of the passage.
  5. Shaft Connection Positive disc to shaft connection by the help of key.
  6. Bearing System Self lubricating plain bearings reduce shaft friction and operating torque. These bearings keep the disc in center and prevent axial movements.
  7. Shaft Sealing Double O-ring shaft sealing system ensures maintenance free sealing for life span.
  8. Top Flange All butterfly valves are equipped with ISO top flanges for all types of actuator-operator connections.
  9. Lifting Holes and Feet Integral lifting holes provide easy installation and feet ensure strong ground support.
  10. Body Seat Stainless steel weld filled and finished integral body seat ensures a corrosion, erosion resistant seat face.
  11. Coating Fusion bonded epoxy, two pack epoxy, solvent-free epoxy, coal tar epoxy.
