Introduction to the Technical Principles and Characteristics of Sanitary Multi channel Diaphragm Valve

The working principle of the hygiene grade multi-channel diaphragm valve is based on the up and down movement of the diaphragm to achieve the opening and closing of the valve. When the valve stem is in the upper position, the diaphragm bends upwards, forming a conductive state that allows fluid to pass through; When the valve stem moves from top to bottom, it drives the valve core to bend the diaphragm and tightly adhere to the valve seat area, thereby closing the flow path of the pipeline fluid. This design enables the valve to respond quickly and effectively isolate the medium during the opening and closing process.

Good sealing performance: The diaphragm made of soft sealing materials such as rubber or plastic has good sealing performance, which can ensure the purity of the fluid and prevent leakage.

Strong corrosion resistance: The diaphragm and valve body materials can be selected according to the characteristics of the medium, suitable for various corrosive or suspended particle media.

Flexible operation: It can be manually operated or controlled through pneumatic or electric means, making the operation simple and fast.

Simple structure: composed of a few components such as valve body, diaphragm, and valve cover, easy to disassemble and repair.

Sanitary grade multi-channel diaphragm valves are widely used in various fields due to their excellent performance characteristics

Pharmaceutical industry: used for process control valves, quantitative feeding valves, sampling valves, and sterile discharge valves to ensure sterility and accurate control in the drug production process.

Food industry: Used as a guiding device, such as sampling valves, quantitative feeding valves, etc., to maintain the purity and safety of food during production and processing.

Chemical industry: used for the transportation and control of corrosive or viscous media, such as mud, pharmaceuticals, textile adhesives, etc.

Other industries: such as power, electroplating and other industrial water treatment fields, as well as the production process of semiconductor wafers.

Installation and maintenance of sanitary grade multi-channel diaphragm valve:

Installation precautions:

Before installation, carefully check whether the operating conditions of the pipeline are consistent with the scope of application specified by the valve.

Before installation, the inner cavity should be cleaned to prevent dirt from blocking or damaging the sealing components.

Ensure that the valve is tightly connected to prevent leakage.

Maintenance points:

Regularly check the wear of the diaphragm and replace it if necessary.

Keep the valve clean and dry, avoid moisture and corrosion.
