Suited for high-pressure piping in oil & gas, petrochemical, and power plant applications requiring compact, small-bore forged valves rated to ANSI Class 150# or 300#.
The valve’s wedge moves vertically within the forged body to control flow, driven by the handwheel or motorized actuator rotating the stem. When open, the wedge lifts fully clear for unrestricted flow. To close, the stem lowers the wedge until it seats firmly against the seat ring, blocking flow completely. Gland packing seals the stem against leakage, ensuring dependable shut-off even under high rated pressures.
Allied Engineering manufactures Forge Steel Gate Valves in 150# & 300# classes using forged materials engineered for high-pressure reliability. With API 602 compliance, rigorous API 598 testing, and years of industry experience, we deliver valves built for dependable, long-term performance.
