bonneted knife gate valve

Product Overview

The Bonneted Knife Gate Valve is a robust, high-performance valve designed for isolating and controlling the flow of slurries, solids, and other challenging media. It is widely used in industries such as mining, wastewater treatment, pulp and paper, and chemical processing. This valve combines the cutting power of a knife gate with the enhanced sealing capability of a bonneted design, making it ideal for handling aggressive, viscous, or abrasive materials.

The bonneted design ensures superior sealing, preventing leakage and protecting the valve internals from harsh external environments. The gate blade is specifically designed to cut through slurries, viscous fluids, and solid-particle-laden streams while maintaining an excellent seal. This makes the bonneted knife gate valve highly effective for applications requiring isolation and flow control in severe conditions.

With sizes available up to DN1800, this valve can handle a wide range of large-scale applications, offering flexibility in design and operation for a variety of industrial needs.

Product Features

Bonneted Design：The bonneted construction enhances the valve's sealing capabilities. The bonnet provides extra support for the stem and gate mechanism, effectively isolating the valve internals from external pressures, contaminants, and corrosive substances, while maintaining a leak-free operation. This design is ideal for systems where external pressures or leakage prevention is critical.

Knife Gate Blade：The blade design of the knife gate valve is engineered to easily cut through slurries, thick fluids, and solids. The gate is typically made of stainless steel or other hard-wearing materials, ensuring long service life and minimal wear, even in abrasive applications.

Durable Materials：The body and bonnet are usually made from cast iron, carbon steel, or stainless steel, offering excellent resistance to corrosion, erosion, and impact damage. This makes the valve durable and reliable in harsh industrial environments.

Reliable Sealing：The bonneted design ensures zero leakage by providing a strong seal between the valve body and bonnet. This is particularly important for preventing leakage in systems handling aggressive or hazardous media.

Standardized Design：The valve is available in a variety of sizes and pressure ratings, and it adheres to international standards, making it easy to integrate into existing piping systems. The bonneted knife gate valve can be configured with various actuators, such as manual, electric, or pneumatic, to suit different operational needs.

Wide Range of Connection Options：The bonneted knife gate valve comes with a range of connection options, including flanged, wafer, or lug type connections, providing flexibility for installation in various piping systems.
