Bevel gear knife gate valve

Product Overview

The Bevel Gear Knife Gate Valve is designed for reliable, high-performance flow control in large-diameter pipeline systems, especially in sizes DN400 and above. This valve is ideal for cutting through thick, viscous media such as slurries, pulp, and solid-particle-laden fluids, making it an essential solution in industries like water treatment, mining, pulp and paper, and chemical processing.

Equipped with a bevel gear drive system, the valve ensures smooth and precise operation, significantly reducing manual torque, especially for large-diameter valves. This gear system is particularly useful in medium to large valves, making it easier to handle high-pressure and high-load conditions.

The knife gate valve is available with a variety of connection types, including flanged, wafer (sandwich), and lug configurations, providing flexibility to meet specific installation and system requirements.

Product Features

Bevel Gear Drive System：
The bevel gear mechanism enables smooth, low-torque operation of the valve, making it ideal for large-diameter valves such as DN400 and above. It reduces manual effort, allowing for precise and controlled valve operation under heavy-duty conditions.

Knife Gate Design：
The knife gate design features a sharp blade that slices through slurries, pulp, and solid-laden fluids, ensuring effective sealing and flow control, even with thick or viscous media. This blade is designed to minimize wear, ensuring consistent performance and reliability.

Durable and Robust Construction：
The valve body is made of high-quality materials such as cast iron, carbon steel, or stainless steel, offering excellent resistance to corrosion, abrasion, and wear. This ensures that the valve performs reliably over a long service life in harsh environments.

Flexible Connection Options：
The valve is available in multiple connection types, including:

● Flanged: Suitable for installation in systems with flange connections, providing secure and leak-free operation.

● Wafer (sandwich): Ideal for installations where space is limited, allowing the valve to be mounted between two flanges.

● Lug Type: Offers bolting opportunities on both sides of the valve, providing additional support and preventing potential leakage.
Bidirectional Flow Control：The knife gate valve is designed for bidirectional flow, allowing it to effectively control the flow direction in both upstream and downstream applications.

Minimal Maintenance Requirements:Thanks to its simple design and durable sealing components, the knife gate valve requires minimal maintenance, reducing downtime and operational costs.

High Sealing Performance:The valve provides reliable sealing in challenging applications, ensuring zero leakage even when handling abrasive or particle-laden fluids.

Advantages

Efficient for High-Pressure and Large Size Applications: The bevel gear mechanism is ideal for large valves, providing enhanced control and precision during operation. This makes it well-suited for pipeline systems with high pressure and large diameters.

Ease of Operation: The bevel gear makes manual operation easier and more controlled, especially for larger valves where handwheels may be insufficient for efficient actuation.

Durability and Reliability: With its durable construction and high-quality sealing elements, the bevel gear knife gate valve is highly resistant to wear, corrosion, and extreme conditions, ensuring a long lifespan even in demanding environments.

Versatility in Media Handling: The knife gate’s design enables it to handle slurries, solids, and viscous liquids, making it ideal for industries dealing with challenging media types.

Minimal Leakage: The valve is designed to minimize leakage through tight sealing, ensuring reliable performance in systems where leakage control is critical.
Cost-Effective Operation: Due to its durability and low maintenance needs, the bevel gear knife gate valve offers long-term cost savings, reducing both operational and maintenance expenses.
