Product Description
AGB Gate Valves are engineered for full-bore, bi-directional isolation in high-pressure oil, gas, and power generation pipelines. The through-conduit slab gate design eliminates internal cavities that trap media, making them ideal for pigging operations and services where product contamination must be avoided.
Metal-to-metal seating ensures reliable shutoff even in high-temperature, erosive, or sour service conditions per NACE MR0175. The rising stem design provides a clear visual indication of valve position, while the bolted bonnet allows for easy in-line maintenance without removing the valve from the pipeline.
Available in slab gate and wedge gate configurations, with options for OS&Y (outside screw and yoke) or non-rising stem. All valves are supplied with a full material traceability package and factory hydrostatic test certificate.
