Elastic sphere
The ball of the pneumatic ball valve is elastic. The ball and valve seat seal ring are made of metal materials, and the sealing pressure is very high. The pressure of the medium itself cannot meet the sealing requirements, so external force must be applied. This valve is suitable for high temperature and high pressure media.

The corrugated pneumatic butterfly valve has many characteristics, such as good flexibility, fatigue resistance, high pressure resistance, temperature resistance, corrosion resistance, etc. Its service life is much longer than other hoses (rubber and plastic hoses), so it has higher comprehensive economic benefits. With the development of modern industry, your demand for high temperature and high pressure resistant corrugated hoses is growing.
Scope of application of flexible hoses: flexible walk pipes are required to avoid vibration, and are applicable to steam, gas, air, heavy oil, petroleum, chemicals, etc.
Brief introduction and functions of pipeline compensator
Pipe compensator, also known as elastomer or elastic joint, expansion joint operation, is mainly used to compensate for thermal expansion and cold contraction of pipes caused by temperature changes. It is assumed that the pipe cannot expand or shorten freely when the temperature changes, and thermal stress will occur in the pipe. This kind of stress must be considered in pipeline planning, otherwise it may lead to the unity of the pipeline and affect the stop of normal production. As an important part of pipeline engineering, compensator plays an important role in ensuring long-term normal operation of pipeline.
