VKRIA - DUAL BLOCK® regulating ball valve

DUAL BLOCK® regulating ball valve with female ends for solvent welding, metric series.

The VKR DUAL BLOCK® valve combines high reliability and safety aspects typical of VKD full bore ball valves with the new flow adjustment function with typical linear curve that meets the most stringent needs typical of industrial applications.

Main features:

  • HIPVC ergonomic multifunctional handle with position indicator and tool to adjust the ball seat carrier
  • Flow direction and opening angle indication plate with graduated scale with 5° detail for clear and accurate readings
  • 90° operating angle that permits the use of standard quarter turn actuators
  • The patented ball design provides linear flow adjustment throughout its range of operation even when the valve is open just a few degrees and guarantees minimum pressure drops
  • Patented DUAL BLOCK® system: prevents union nuts from loosening even under extreme operating conditions: e.g. vibration or thermal expansion
