Valbart Srl Through Conduit (T.C.) Gate Valves are manufactured with a full bore, slab gate, rising stem OS&Y and with floating seats pressure energized for a positive and bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are 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 same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.

Major features are:
