The all-copper butterfly stem ball valve is a valve that combines the easy operation of a butterfly valve with the reliable sealing performance of a ball valve. It is widely used in pipeline systems for water, oil, gas, and other media. The all-copper butterfly stem ball valve is made of brass or solid copper, offering excellent corrosion resistance and durability. Its design feature is a butterfly-shaped handle (butterfly stem), which makes opening and closing more convenient and quick, suitable for applications requiring frequent adjustments. This type of valve is typically used in pipeline systems ranging from DN15 to DN100, catering to water, oil, gas, and other media.

● Product features

Lightweight operation: butterfly handle design, 90 rotation can achieve full open or full close, small operating torque, save effort.

Seal reliability: use soft seal (such as nitrile rubber, fluororubber, etc.) or metal seal to ensure zero leakage.

Compact structure: small volume, light weight, suitable for space limited installation environment.

Corrosion resistant: the full copper material is suitable for water, oil, gas and weak corrosive media.

Convenient maintenance: the sealing element can be replaced to extend the service life of the valve.

● Applicable fields

Water supply and drainage system: municipal water supply, building pipeline, etc.

HVAC: Used for hot and cold water circulation system.

Industrial pipeline: medium and low pressure fluid control in chemical, food, medicine and other industries.

Ship system: some models are specially designed for Marine use and resistant to seawater corrosion.

● Installation and maintenance precautions

Ensure that the pipe threads match during installation to avoid excessive tightening that may cause deformation of the valve body.

Check the wear of the seal regularly and replace it if necessary.

Avoid use in pipelines containing solid particles or highly corrosive media to prevent damage to the sealing surface.
