A wedge-shaped gate component for precise fluid flow regulation in industrial valves.
The gate/wedge is a critical component in gate valves, consisting of a solid wedge-shaped disc that moves perpendicular to the flow direction to open or close the valve. It provides tight shut-off by wedging between two parallel or inclined seats, creating a metal-to-metal seal that prevents leakage in high-pressure applications. This component is engineered for minimal pressure drop when fully open and is commonly used in applications requiring straight-line flow with minimal turbulence.

Solid wedges are one-piece construction suitable for consistent temperatures, while flexible wedges have cutouts allowing slight deformation to improve sealing across varying temperatures and pressures.
Annual visual inspection with pressure testing every 3-5 years depending on service conditions. Critical applications may require more frequent NDT examination.
Minor seat damage can be repaired by machining and lapping, but severely eroded or cracked wedges require complete replacement for safety.
