A type of valve whose opening and closing element is a spherical body and rotates around an axis. It is mainly used for quickly cutting off, distributing and changing the flow direction of the medium.

The valve has a butterfly plate as the opening and closing element and rotates around a fixed axis. It is used for regulating and cutting off the pipeline.

Gate valve (full-bore shut-off), globe valve (shut-off and regulation), check valve (anti-backflow), used in almost all industrial pipeline systems in petrochemical, refining and chemical, power, coal chemical and other industries.

Valves specifically designed for low-temperature media (such as LNG, liquid nitrogen, liquid oxygen, etc.) usually refer to those with a working temperature lower than -46℃ (-50°F).

Small valves connected to the pipelines of instruments or measuring equipment, used for sampling, measurement, isolation or pressure relief, etc.

Special valves developed for extreme or special environments that exceed the conventional design conditions of valves.
