Design and Operation
The signature design consists of a solid blind plate for complete flow interruption, a spacer ring for unrestricted flow, and a connecting metal handle for rotation. When switching between modes, operators simply loosen the flange bolts, rotate the handle 180 degrees, and retighten. This streamlined operation typically takes 5-10 minutes, compared to 30-60 minutes for traditional blind plate replacement. A black anti-rust coating protects the surface against corrosion, ensuring long-term reliability and durability.
