Sanitary stainless steel quick-install butterfly valve product details:

Sanitary stainless steel quick-install butterfly valve uses advanced standard electronic polishing technology to make the valve surface smoother and cleaner, and there will be no medium accumulation area during long-term use, which can effectively avoid potential pollution. The valve is easy to install and disassemble, and the downtime maintenance time is fast, which can be shortened to the greatest extent. This product is mainly used in dairy products, food, pharmaceuticals, beer, cosmetics, clean steam, beverages, and biochemical industrial process control occasions.

The main features of sanitary stainless steel quick-install butterfly valve are:

1. Novel structure, reasonable design, simple operation, light weight, fast and agile opening and closing.

2. Small operating torque, easy installation and disassembly, and smart use.

3. It can be installed at any position and is easy to maintain.

4. The sealing material has the advantages of aging resistance, corrosion resistance, and long service life.

· Working principle of quick-install butterfly valve

The quick-install butterfly valve is a valve that uses a circular butterfly plate as an opening and closing part and uses a valve stem to rotate the opening and closing and adjust the fluid channel. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. The butterfly valve body is in the cylindrical channel, and the disc-shaped butterfly plate can rotate around the axis. The standard rotation angle is about 0°~90°, and it will reach the fully open state when it rotates at 90°.

When the valve is fully opened, it has a very small flow resistance. When the opening direction is between 15° and 70°, it can perform rapid flow control, so when adjusting large diameters, the butterfly valve should have a very wide range. The valve plate of this butterfly valve has a wiping motion function. When welding the butterfly valve, it can be used with media with suspended fixed particles. Depending on the strength of the seal, it can also be used for powdery and granular media.
