Product Overview

Bevel Gear Knife Gate Valves are designed for reliable, high performance flow control in large diameter piping systems, especially for diameters of DN400 and above. Ideally suited for cutting viscous media such as slurries, pulp and fluids containing solid particles, the valves are an essential solution for industries such as water treatment, mining, pulp and paper and chemical processing.

The valves are equipped with a bevel gear system that ensures smooth and precise operation and significantly reduces manual torque, especially for large diameter valves. The gear system is particularly suitable for medium and large valves, making it easier to cope with high pressure and high load conditions.

Knife gate valves are available in a variety of connection types, including flanged, clevis and lugged, providing flexibility to meet specific installation and system requirements.

Product Features

Bevel gear drive system:
The bevel gear drive mechanism provides smooth valve operation with low torque, making it ideal for valves with large diameters of DN400 and above. It reduces manual operation and enables precise and controllable valve operation even under heavy-duty conditions.

Knife gate design:
Knife gates are designed with sharp blades that cut through slurries, pulp and fluids containing solid particles, ensuring effective sealing and flow control even in thick or viscous media. The blades are designed to minimize wear and ensure consistent performance and reliability.

Rugged and durable construction:
The valve body is made of high quality materials such as cast iron, carbon steel or stainless steel, which provide excellent corrosion, wear and abrasion resistance. This ensures that the valves can operate reliably for a long time even in harsh environments.

Flexible connection options:
The valve is available in a variety of connection types including:

● Flange connection: Suitable for installation in systems with flange connections to ensure safety and no leakage.

● Mezzanine: For installations where space is limited, the valve can be mounted between two flanges.

● Lug Type: Both sides of the valve can be bolted to provide additional support and prevent potential leakage.
Bi-directional flow control: Knife gate valves are designed for bi-directional flow, allowing for effective flow control in upstream and downstream applications.

Low Maintenance Requirements: The simple design of the knife gate valve and the durability of the sealing components result in low maintenance requirements, thereby reducing downtime and operating costs.

HIGH SEALING PERFORMANCE: The valve provides reliable sealing in demanding applications and ensures zero leakage even when handling abrasive or particulate fluids.

Product Advantages

Efficient for High Pressure and Large Bore Applications: Bevel gear mechanisms are ideal for large valves, providing enhanced control and precision during operation, making them ideal for high pressure and large bore piping systems.

Easy to operate: Bevel gears make manual operation easier and more controllable, especially for large valves where handwheel drive is inefficient.

DURABLE AND RELIABLE: Bevel gear knife gate valves utilize durable construction and high-quality sealing elements that are extremely resistant to abrasion, corrosion, and extreme conditions, ensuring a long service life even in harsh environments.

Media Handling Versatility: Knife gate valves are designed to handle slurries, solids, and viscous liquids, making them ideal for industries handling difficult media.

Leakage minimization: The valve minimizes leakage through a tight seal design, ensuring reliable performance in systems where leakage control is critical.
Cost-effective operation: Due to their durability and low maintenance requirements, bevel gear knife gate valves realize long-term cost savings, reducing operating and maintenance expenses.
