Spiral gate valve
The Spiral Gate Valve is engineered for industrial applications requiring high-pressure and high-temperature control. Its spiral-guided wedge mechanism distributes sealing forces evenly, reducing torque and wear. Designed for tight shut-off, minimal leakage, and long service life, it suits power plants, oil & gas pipelines, chemical processing, and metallurgical systems.
Spiral gate valve
Spiral Gate Valves feature a spiral-wedge design that converts linear motion into uniform sealing force, enhancing tight shut-off under high pressure and temperature conditions. The valve body and wedge materials are selected for corrosion and erosion resistance, ensuring durability in severe industrial environments.
The valve supports flanged, butt-welded, or socket-welded connections and is available with rising stem or non-rising stem designs. OEM customization options include body and seat materials, sealing types, actuator integration, and dimensions to meet project-specific requirements.
Spiral Gate Valves meet international quality and industrial standards:
