VALVES / BALL VALVE
ELECTRICALLY OPERATED V NOTCH SEGMENTED BASIS WEIGHT BALL VALVE-1550 SERIES

Segmented Ball valve is a ball sector valve with metal to metal or metal to PTFE seating. The segmented ball valve combines the best control characteristic of the ball valve and the butterfly valve. It can be used both as a control valve and as a shut off valve. It is available as standard in Stainless steel. It is also available in other materials based on the application.

V-Notch Ball Valve Features

  • A one-piece, leak-proof stainless-steel body, with face to face lengths in acc. with IEC standards
  • A ball sector with top and bottom bearings for low operating torque so that low torque actuators can be used
  • A 'V' shaped sector that provides accurate control over a wide range, even at low flow rates and if used for viscous media with high concentrations of solid particles.
  • A spherical area of the ball sector which, with PTFE seat gives tight closing. The Sterlite seat ring ensures excellent tightness at all differential pressures. The maximum leakage in the direction of flow is less than 5 x 10⁻⁶ of the Kv value in this case.
  • Meatoplasty bearings
  • O ring or graphite packing for the stem gland
  • The standard stellate seat can easily be converted to PTFE after turning the ball sector by 180 degrees, without the need to dismantle the valve.
  • Are designed to overcome the problems of harsh, particle entrained processes.
