Type 567 incorporates a double eccentric operating principle that provides improved wear. Typical applications for the corrosion-resistant butterfly valve, which is available in large diameter sizes up to 12", include wastewater systems in chemical, chemical distribution, electroplating and power plant operations. The design offers an off-center shaft that allows the disc to completely disengage from the disc seal, even when partially open. This reduces seal friction and improves seal wear characteristics, resulting in longer service life, minimal maintenance and better protection against pressure surges.
