Supplier-named four-dimensional eccentric bidirectional sealing design.
Yangquan calls this family a four-dimensional eccentric bidirectional hard-seal butterfly valve. The entry addresses applications requiring sealing under flow or pressure from either direction. Define the actual forward and reverse operating conditions, then confirm the selected sealing arrangement, actuator and test requirements with the supplier without treating the catalog’s design claims as independently verified performance.
