What is the function of the PVC handle butterfly valve

The PVC handle butterfly valve is a type of valve made of polyvinyl chloride. Its characteristic lies in controlling the opening and closing of the valve disc by rotating the handle, thereby achieving the regulation of fluid flow. This type of valve is typically used in liquid or gas pipeline systems as a shut-off, regulating and throttling device.

The following are some main features of the PVC handle butterfly valve:

Material advantages: PVC is a lightweight, corrosion-resistant and non-toxic plastic material with excellent weather resistance and chemical stability, suitable for a variety of fluid media.

Compact structure: The structural design of PVC handle butterfly valves is usually compact, occupying less space and facilitating installation and layout in pipeline systems.

Easy operation: The opening and closing of the valve can be easily controlled by rotating the handle, which is simple and fast.

Good sealing performance: Elastic sealing materials are used between the valve disc and the valve seat, which can provide excellent sealing performance and prevent fluid leakage.

Wide application range: PVC handle butterfly valves are suitable for various fluid media, such as clear water, sewage, corrosive liquids and certain gases, and are widely used in construction, chemical industry, environmental protection, water supply and drainage and other fields.

Economical price: Due to the relatively low cost of PVC material, the price of PVC handle butterfly valves is also relatively economical, making them suitable for large-scale application.

When using PVC handle butterfly valves, the following points should be noted:

Make sure to apply moderate force when operating the handle to avoid excessive force causing damage to the valve.

Regularly inspect the sealing performance and operational flexibility of the valve. If any abnormality is found, it should be dealt with promptly.

Avoid installing the valve in an environment with excessively high or low temperatures to prevent affecting its service life.

Select the appropriate valve material and sealing material based on the nature of the fluid medium to ensure the corrosion resistance and sealing performance of the valve.
