Pneumatic Expansion Concentric Butterfly Valve

Waits's self-developed Pneumatic expansion concentric butterfly valve are ideal for lithium battery powder and bulk material transfer. An integrated control module inflates the seal during closure for zero leakage, and rapidly deflates to eliminate friction on opening. This extends service life and lowers maintenance costs—perfect for new energy material pipelines.
