VATTEN pneumatic expansion butterfly valve, with its self-developed pneumatic module and valve body, has demonstrated excellent performance in various industries. It has become a reliable choice, especially in the powder and lithium battery sectors, where stability and high efficiency are paramount. The valve body is designed with high-strength materials, ensuring excellent durability even in harsh environments.
The valve's sealing performance is enhanced by the use of wear-resistant EPDM and VITON materials. These materials are highly resistant to wear and corrosion, significantly extending the valve's service life. Under high pressure, high temperature, and other complex conditions, the valve's sealing remains stable and reliable.
Additionally, the valve's sealing system has been optimized to meet strict zero-leakage standards. This ensures that the VATTEN pneumatic expansion butterfly valve effectively prevents leaks in industrial applications with high sealing requirements, guaranteeing the safety and stability of the production process
