GTX series double expanding gate valves

Features & Benefits

GTX series valves are specifically design for on-off services and are suited to withstand all types of high abrasive services under high pressure and temperature conditions. The valve is equipped with a wedge and segment. The system achieves its positive seal capacity by mechanically expanding the gate and segment against the seats due to the thrust exerted by the stem.

In both in closed and open position, the expansion creates a tight seal against the upstream and downstream seats. During the valve stroke, this unique design resists expansion of the gate, allowing it to slide, avoiding wear of seats and gate. Valves are piggable in the fully open position and generate pressure drop across the valve equal to the inside diameter of the connecting pipe. Material selection is fully customizable to meet customers project specifications.
