FIP has developed a VKD DUAL BLOCK® ball valve to introduce a high reference standard in thermosplastic valve design.VKD is a True Union ball valve that meets the most stringent needs required by industrial applications.

  • Connection system for socket welding, butt welding and flanged joints
  • Patented SEAT STOP® ball seat carrier system that lets you micro-adjust ball seats and minimise axial force effects
  • Easy radial disassembly allowing quick replacement of O-rings and ball seats without any need for tools
  • PN16 True Union valve body made for PVDF injection moulding equipped with built-in bores for actuation. ISO 9393 compliant test requisites
  • Option of disassembling downstream pipes with the valve in the closed position
  • Full bore ball with high surface finish
  • Integrated bracket for valve anchoring
  • Possibility of installing a gear box or pneumatic and/or electric actuators by applying an ISO standard bore PP-GR flange
  • STAINLESS steel co-moulded stem, with square section as per ISO 5211

HIPVC ergonomic multifunctional handle for quick operation, lock and graduated adjustment in 10 positions. Possibility of inhibiting rotation with a lock
Customisable Labelling System: LCE module made of a transparent protection plug and customisable tag holder using the LSE set (available as accessory). The customisation lets you identify the valve on the system according to specific needs
DUAL BLOCK® patented lock system that ensures union nut tightening hold even in severe conditions such as vibrations or heat dilation
Double stem with double O-Rings for ball centring and operating torque reduction
