Through Conduit Slab Gate Valves | Series KS

Through Conduit Slab Gate Valve

Valbart Srl Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with oating seats and gate, pressure energized, for a bubble tight shut o upstream and downstream under both low and high dierential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design.

The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the ow stream and therefore protected from the erosive action of the ow. Pigs and scrapers can be run through the valve without damage.

  • Floating Seat
    The seat ring is installed with springs, this insures constant contact with the gate insuring a tight seal.
  • Bi-directional
    Shut of f both up-stream and down-stream.
  • Stem Seals
    Self energizing non rolling lip seats, no side load or friction drag on the stemlow operating thrust.
  • Steam Protector and position indicator
  • API 6 FA Fire safe design
    Metal to metal primary seal, secondary to be sof t seal.
  • Double Block and Bleed. (DBB)
    valve with two seating surfaces which in the closed position, blocks flow from both valve ends when the cavity between the seating surfaces is vented through a bleed (drain plug) connection provided on the body cavity.
  • Graphite
    Fire safe sealing for body and bonnet connection.
  • Self Relieving Seat
    Protection against over pressure in the body cavity.
  • Body Drain
    Relief of the trapped fluid in valve cavity.
  • Emergency sealant injection for both seats and stem packing
  • Top Entry Bonnet
    Easy inline valve maintenance and replacement of stem packing.
