Knife Gate Valve
The knife gate valve is specifically designed to handle thick liquids, sludges, and solid-liquid mixtures, making it essential in various industrial applications. Its simple design features a metal plate as the gate and lacks a bonnet, allowing for effective slicing action through viscous materials.
Key features include:
Unidirectional/Bidirectional Design: Suitable for different flow directions, depending on the application.
Pressure Tight Isolation: Provides reliable sealing to prevent leaks in water and wastewater treatment, pumping stations, and other industrial processes.
Versatile Applications: Commonly used in paper and pulp mills, power plants, and mining operations due to its ability to manage challenging media.
The knife gate valve is essential for efficient flow control and isolation in environments where traditional valves may struggle.
