VOLFRAM make Cast Steel Flex Gate Valves are tight sealing, easy operation, isolation valves for liquid and gaseous fluids over a wide range of line pressures and temperatures.

Self-adjusting flexible wedge assures tight sealing and minimizes stress concentration under varied service conditions.
Stem-wedge thrust closer to wedge centre for accurate wedge movement.
Long guide ribs in the body to minimize seat wear.

Gate valves are of rising stem, outside, screw and yoke (OS & Y) and with Bolted Bonnet construction. The rising stem indicates open or close position of the valve.
