The large-diameter bevel gear bellows globe valve adopts a bevel gear transmission mechanism, which facilitates effortless operation and is suitable for large-diameter pipeline systems.
○ Nominal diameter: DN200-DN400mm
○ Nominal pressure: PN16-PN64 (corresponding to Class 150 – Class 300)
○ Applicable medium: steam, heat transfer oil, high-temperature water, corrosive or toxic liquid/gas
○ Operating temperature: –40°C to +450°C
○ Connection method: flange connection
○ Valve body material: WCB (carbon steel), stainless steel 304, 316L
○ Bellows material: stainless steel, alloy steel, special steel
○ Bellows structure: multi-layer hydroformed metal bellows
○ Sealing form: full metal bellows seal + graphite auxiliary packing (double guarantee, zero external leakage)
○ Operating mode: Bevel gear transmission (reduces operating torque, facilitating large-diameter opening and closing)
○ Switch direction: Clockwise to Close (S.C. to Close)
○ Design standards: API 602 / BS 5352 / ASME B16.34
○ Structural length: Conforms to ASME B16.10 / GB/T 12221
○ Installation direction: low inlet and high outlet, ensuring tight closure and reducing erosion
○ Bevel gear transmission structure, which is labor-saving and suitable for large-diameter valves.
○ The bellows seal design ensures zero external leakage of the medium, providing safety and reliability.
○ The opening and closing torque is uniform and stable, ensuring no jamming or wear even after long-term use.
○ Strong resistance to high temperature and high pressure, suitable for a variety of harsh working conditions.
○ The valve body structure is sturdy and durable, with long corrosion and fatigue resistance lifespan.
○ The cutoff control points that require manual operation in the large-diameter steam pipe network.
○ High-temperature, high-pressure, corrosive medium conveying pipeline system for petrochemical plants.
○ Manual regulating valves for main steam and bypass pipelines in boilers in the power industry.
○ In metallurgical factories, where high-flow cutoff of hot air or steam media is required.
