Expanding Gate Valve

Fangwen Expanding Gate Valves are manufactured with a full bore port and with 2-piece (gate + segment) obturator designed for a positive, bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and high robustness 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.
