Product Description:

Knife gate valve, also known as knife gate valve or knife gate valve, is suitable for pipelines containing suspended particles and fiber materials such as pulp, sewage, coal slurry, ash and cement mixtures. It is cut off by a blade shaped gate that can cut through fiber materials. The valve body actually does not have a chamber, and the gate plate rises and falls in the side guide groove, and is tightly pressed against the valve seat by the bottom protrusion. If high medium sealing performance is required, an O-shaped sealing valve seat can be used to achieve bidirectional sealing. According to the driving mode, it is divided into manual knife gate valve, pneumatic knife gate valve, and electric knife gate valve.

Knife gate valve is easy to operate and flexible, with small volume, smooth channel, low flow resistance, light weight, easy installation and disassembly. Its nominal size is DN50~DN800, and it can work normally under working pressure of 0.6MPa~1.6MPa and operating temperature ≤ 100 ℃. The blade gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. Stainless steel gate can prevent sealing leakage caused by corrosion.

Product Features:

1. Ultra short structural length saves materials and greatly reduces the overall weight of the pipeline system.

2. Occupying a small effective space, it can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.

3. The gate is made of austenitic stainless steel, which greatly improves its corrosion resistance and can effectively prevent sealing leakage caused by gate corrosion.

4. The upper sealing filler adopts flexible PTFE, which is reliable in sealing and easy to operate.

5. The gate has the function of a knife, which can effectively block various impurities in the medium.
