knife gate valve with pneumatic actuator

Industrial Applications of Knife Gate Valve

Knife gate valves are commonly used in pipelines that transport fluids containing suspended particles. The sharp-edged gate can cut through thick media and provide reliable sealing performance. As a result, these valves are especially suitable for pulp and paper, mining, wastewater treatment, and chemical processing industries.

In addition, the valve design helps reduce pressure loss when the valve is fully open. This feature improves system efficiency and supports smooth material flow. Furthermore, the lightweight structure makes installation and maintenance easier.

Features of Pneumatic Knife Gate Valve Design

The knife gate valve with pneumatic actuator uses a unidirectional wafer knife edge design for industrial on-off applications. The body and seat structure helps prevent clogging when handling fluids with fine particles. Moreover, the beveled knife edge allows the gate to cut through thick media smoothly.

GMK VALVE offers different configurations based on various operating conditions. These options include non-rising stem knife gate valves, wafer knife gate valves, lugged knife gate valves, pneumatic knife gate valves, electric knife gate valves, manual knife gate valves, and bevel gear knife gate valves.

Durable Body Construction

The body design includes guide claws at the port bottom to secure the gate position. Therefore, it eliminates the need for a traditional groove that may cause particle buildup. This design helps improve flow performance and reduces the possibility of leakage.

Furthermore, the integral body structure provides easy assembly and stable operation. It also supports a compact design for different industrial pipeline systems.

Reliable Gate and Sealing Performance

The beveled knife edge provides strong cutting force and improves sealing performance. As a result, the gate can handle thick and challenging media effectively. In addition, the PTFE resilient point guide prevents direct metal contact between the gate and body.

The gate thickness can also be increased for higher pressure applications. Therefore, customers can select suitable configurations according to different operating requirements.
