A comprehensive analysis of the functions, applications, and characteristics of Chinese manual knife gate valves

In the industrial field, valves are important equipment for controlling fluid flow. Among them, manual knife gate valves are widely used in various industries due to their unique design and superior performance. This article will provide you with a detailed introduction to the functions, uses, and product features of manual knife gate valves.

Function and purpose

Manual knife gate valve, as its name suggests, is a type of valve that uses knife gate plates and has good shear performance, especially suitable for difficult to control fluids such as slurry, powder and fiber. This type of valve is widely used in industries such as papermaking, petrochemicals, mining, drainage, and food. According to on-site control requirements, electric or pneumatic actuators can also be equipped to achieve automatic operation of valves.

Product features

1. Ultra short structural length: The design of the manual knife gate valve is compact, saves materials, and can significantly reduce the overall weight of the pipeline system.

2. Small footprint: This type of valve occupies less effective space, which can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.

3. Strong corrosion resistance: 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. Reliable sealing: The upper sealing filler adopts flexible PTFE, ensuring the reliability of the sealing and making the operation more lightweight and flexible.

5. Effectively cutting off impurities: The gate has the function of a knife, which can effectively cut off various impurities in the medium.

6. Wide range of applicable temperature and pressure: Made of hard sealed stainless steel material, the valve disc is spray welded, which can expand the valve's requirements for temperature and pressure.

technical standard

The production and application of manual knife gate valves follow a series of strict technical standards, including GB/T26480, GB/T9113, JB/T79, JB/T8691, GB/T12221, HG/T20592, EN1092, etc. These standards cover aspects such as design specifications, connecting flanges, testing and inspection, structural length, and product specifications.

Overall, manual knife gate valves are a very practical and efficient industrial equipment, demonstrating excellent quality in design, use, and performance. When selecting valves, manual knife gate valves are undoubtedly an excellent choice worth considering.
