VKD Series True Union Ball Valve

The next generation industrial valve features the patented Dual Block® system.

  • A patented seat stop carrier
  • High quality stem and ball support system
  • Integral mounting flange and bracketing

 

The next generation industrial valve features the patented Dual Block system which allows locking of the union nuts in a preset position, assuring seal integrity under severe service conditions. A patented seat stop carrier, high quality stem and ball support system, integral mounting flange and bracketing, and a multifunctional locking handle (standard on sizes 2-1/2" to 4") set this valve apart from the rest. The VKD is available in PVC, CPVC, PP, and ABS with PTFE seats and either EPDM or FPM seals.
