6400 Series Double Block & Bleed Plug Valve – For Positive Shut-Off

6400 Double Block and Bleed Plug Valve (DBBV) dual expanding Plug Valve and non friction Double Tight shut-off valve in both the up and down stream.

Description

6400 Double Block and Bleed Plug Valve (DBBV) dual expanding Plug Valve and non friction Double Tight shut-off valve in both the up and down stream.  

  • No Maintenance and the valve reduces space.  The 6400 series has two seated surfaces (slips).
  • When the valve is in closed position each individual seal is fully isolating, not allowing any leakage from downstream, upstream nor from the body cavity.
  • A thermal relief vents / bleeds the body cavity when overpressure occurs so the downstream pipeline is fully isolated from upstream pressure without there being pressure balancing necessary.
