Double Flange Pneumatic Knife Gate Valve

The Double Flange Pneumatic Knife Gate Valve is an industrial fluid control device composed of a pneumatic actuator, a knife-type gate, a valve body, and a double flange connection end. It is driven by compressed air to achieve precise cut-off control of media containing solid particles, slurry, etc.

Excellent material
The valve body is made of WCB or SS304 stainless steel, and the internal key components are made of STL alloy and 304 stainless steel. It has high strength and excellent corrosion resistance and is suitable for complex working conditions containing corrosive or highly abrasive media. The service life of the whole machine can exceed 100,000 opening and closing cycles.

High sealing reliability
The Double Flange Pneumatic Knife Gate Valve adopts a PTFE or metal elastic sealing ring design. The valve plate and seat fit tightly in the fully closed state. The sealing level reaches ANSI Class VI, which effectively prevents medium leakage and is suitable for applications with strict sealing requirements.

Fast drive response
Driven by an efficient pneumatic actuator, the Double Flange Pneumatic Knife Gate Valve can complete a 90° opening and closing action within 1 to 3 seconds, more than 70% faster than traditional manual or electric knife gate valves.

Strong installation stability
Due to the double flange structure design, the centering is excellent after installation, avoiding leakage or misalignment caused by deviation, so that the Double Flange Pneumatic Knife Gate Valve can maintain a stable connection under high vibration and high-pressure conditions.

1. Before installation, check the valve cavity and sealing surface, and no dirt or sand is allowed to adhere to it. This type of valve should generally be installed horizontally in the pipeline.

2. The bolts of each connection part are required to be tightened evenly.

3. Check the packing part to be compressed, not only to ensure the tightness of the packing, but also to ensure that the ram opens flexibly;

4. Before installing the valve, the user must calibrate the valve model, connection size, and pay attention to the flow direction of the medium to ensure consistency with the valve requirements.

5. When installing the valve, the user must reserve the necessary space for the valve drive.

6. The wiring of the drive device shall be carried out according to the circuit diagram.

7. The pneumatic knife gate valve must be maintained regularly, and shall not be collided with and squeezed at will, so as not to affect the seal.
