Bonney Forge’s bellows seal gate and globe valves are engineered for applications requiring high reliability and minimal emissions. These valves are available in two bonnet designs to cater to different operational requirements:

• Bolted Bonnet Design: Features a robust male-female joint with a spiral wound gasket made from F316L/graphite, ensuring a secure seal. Ring joint gaskets are available upon request for higher pressure applications.
• Welded Bonnet Design: Incorporates a threaded and seal welded joint, with an option for a full penetration strength welded joint for enhanced durability.

Bellows sealed valves are available in both gate and globe valve configurations, providing versatility for various industrial applications.

Key Features:

• Construction: Bolted or welded bonnet types with flanged valves integral with the body forgings.
• Gasket Design: Spiral wound gaskets are standard up to ASME 1500; ring joint gaskets are standard for ASME 2500 and above, with SPW/RJ available on request.
• Packing: High-quality packing compliant with API 622 for reliable tightness and low emission performance, fully compliant with API 624.
• Design: Outside Screw and Yoke (OS&Y) with a low operation torque design and self-aligning two-piece packing gland.
• Bellows Seal: Seal welded bellows designed to isolate valve packing from potentially caustic gases, ensuring enhanced safety and performance.
